Cups 2.0.0 high cpu

nmset · 2014-12-28 11:09:13

I investigated with perl packages on two hosts concerning the "/usr/bin/perl /usr/lib/cups/drivers/foomatic list" block. After removing completely perl-clone (pacman -Rcc), the problem got resolved. Both the cups web interface and "lpinfo -m" work normally. How and why did perl-clone interfere ? don't know, don't know perl language at all, someone knowledgeable in perl should investigate.

I don't have the package perl-clone installed - so that solution would not be relevant to my cups issues. Why it matters for yours I don't know.

The foomatic list command blocks whenever I have foomatic-db-engine installed.
I have tried removing packages and configuration, reinstalling everything again.
As soon as foomatic-db-engine is installed, it stops working.

So now I am trying to figure out how to debug foomatic...

Did you check this out? https://bbs.archlinux.org/viewtopic.php … 9#p1472149

I have foomatic-db-engine installed with no problems.

Thanks for the tip, but no, deleting the file does not help.
Also, I am not even getting any error messages - the foomatic command simply blocks.

I narrowed it down to line 101 in /usr/lib/cups/driver/foomatic:

    $db->get_overview(1, 1 + $listreadymadeppds);

I put in some debug printing before and after the line, and it clearly blocks on this exact spot.
I wonder why, or how I should continue from here...

Oh, wait, the command completed!!

I left the "foomatic list" command running in the background for a very long time, grinding a core on my i7-4600U, and it finally returned.

I wonder why that specific line took so long to complete. I am timing it now...

*EDIT*

Ok, I kinda found the culprit: gutenprint

Removing the gutenprint package resolved my problem, and foomatic no longer hangs for 13+ minutes.

This is how it looks:
* /usr/lib/cups/driver/foomatic line 101 calls get_overview from Foomatic::DB
* /usr/lib/perl5/vendor_perl/Foomatic/DB.pm line 1741 calls parseOverview from Foomatic::DB::filters::xml::xmlParse
* /usr/lib/perl5/vendor_perl/Foomatic/filters/xml/xmlParse.pm "hangs" during the loop starting at line 768

Below is the loop from xmlParse.pm
The driverName it "hangs" on is gutenprint-ijs.5.2

	#DRIVER DRIVEN, ADD DRIVER DATA TO PRINTER
	foreach my $driverName (keys %drivers) {
		my $driver = $drivers{$driverName};
		if (($cupsMode) && ((!$driver->{'cmd'}) &&
				    (!$driver->{'cmd_cmd'}))) {
			next; # In CUPS mode a driver that lacks a cmd or a
			      # pdf_cmd (cmd_cmd) is useless and should not
			      # appear in overview. Note that here we do
			      # no need to consider that there could be
			      # also a ready-made PPD file (CUPS mode 2), as
			      # the links to the PPDs are in the printer
			      # entry files and here we do not have a
			      # printer entry.
		}
		foreach my $printer (@{$driver->{'printers'}}) {
			if($printer->{'id'}) {
				my $id = $printer->{'id'};
				
				if (!$printers{$id}) {#create new no xml printer
					$printers{$id} = $this->getNoXmlPrinter($id);
				}
				
				#add driver to printer's list of drivers
				push(@{$printers{$id}->{'drivers'}}, $driverName);
				
				#add driver data to printer
				$printers{$id}->{'driverproperties'}{$driverName} = $this->getPrinterSpecificDriver($driver, $printer, 0);
			}
		}
		delete $driver->{'printers'}; #cleans out the driver's printers array
	}

I added this line at the top of the outer foreach loop to find the driverName:

		print STDERR "DEBUG: driverName: $driverName\n";

Adding another debug line to the inner foreach loop reveals that the gutenprint-ijs.5.2 driver contains thousands of printers, which, for some reason, take a huge amount of time to process.

Hi,

This makes sense. However, I dont have the foomatic-db package installed and do not have a /usr/lib/cups/driver/foomatic file or a /usr/lib/perl5/vendor_perl/Foomatic directory. So I assume, if the loop through the models is the culprit, that an equivalent xmlparse is occuring somewhere else. It seems I must use the gutenprint package for an acceptable driver for my Cannon MX 920 printer, so uninstalling it is not an option for me.

Perhaps removing all of the printers I don't need from the xml file itself is a possible solution. Shooting in the dark, I tried removing the extraneous printers from the xml files located at /usr/share/foomatic/db/source/driver/gutenprint-ijs.5.2.xml and /usr/share/foomatic/db/source/driver/gutenprint-ijs-simplified.5.2.xml and /usr/share/gutenprint/5.2/xml/printers.xml. However, that did not solve the extended high-cpu demand that occurs with administrative tasks. I have subsequently restored my original files. Perhaps I am looking in the wrong xml file... but darned if I can find another. More likely, I'm simply over my head.

Here is another quandry that is perhaps related. The printer is on the LAN. To see it, I start the following services: avahi-daemon.service, org.cups.cupsd.service, and cups-browsed.service. I used to have these enabled at boot but now I deliberately start them when I need to print and stop them when finished. The reason I do this is that I have found that, at shutdown, I get a hung avahi stop job about 5% of the time when these three services are running, For me, explicily starting/stopping the services is not a nuisance but there are several other Arch users on the network with independent installs that have the same random stop job hang.

Happy New Year everybody!

Had the same problem here with a Brother HL-2035 on USB2 with cups 2.0.1-1 installed.
Removing gutenprint doesn't change anything, instead modifying /etc/cups/client.conf as mentioned before (#22) was the solution for me.

Taylan wrote:

Modifying /etc/cups/client.conf worked for me, see this post on another thread https://bbs.archlinux.org/viewtopic.php … 6#p1482856

Now the high CPU usage is back to normal, when:
- switching the printer on
- printing
- performing certain printer commands (i.e. lpinfo -v)

However when I'm administrating the printer via localhost:631 the CPU uses still about 96%.

I had another look at this issue on my machine. Firstly I uninstalled gutenprint as it was not needed for my printer (Samsung MFP) but that made no difference to the high CPU issue. Then I stopped the org.cups.cupsd service that had been started by the org.cups.cupsd.socket when the printer had been switched on (and which led to the 100% CPU issue).

With the org.cups.cupsd service stopped I edited /etc/cups/client.conf to have

# see 'man client.conf'
#ServerName /run/cups/cups.sock #  alternative: ServerName hostname-or-ip-address[:port] of a remote server
ServerName localhost:631

and then did

systemctl --system daemon-reload

Then since the change to the file above would presumably then not have socket activation any more I started the org.cups.cupsd service with systemctl. There was no longer any pegging of the CPU at 100%. Setting a print did start the printer which then whirred for around 20 seconds before the print came out but it printed fine with no CPU load at 100%. I also checked that going to localhost:631 in a browser worked fine, and that checking the printer on that web cups interface worked fine without high CPU load.

However if I stop the org.cups.cupsd service then switch off the printer and back on then the socket activation no longer works - but restarting org.cups.cupsd service works fine with no further 100% CPU issues.

So I don't know if this seems to point at the socket activation causing a problem which is avoided by changing the client.conf file to look at localhost:631? If so then presumably the workaround is to disable via systemctl org.cups.cupsd.socket and enable org.cups.cupsd.service so that the cups service runs at boot but socket activation is no longer running?

Perhaps some more investigation into this looking at whether switching socket activation back on brings the problems back might be worthwhile? Also is there any issue with the way the service files have been written for cups socket activation that may be behind this problem?

This is possibly related but needs more research into the connection with the bug in this thread, if any, since this is from almost a year ago:

That file and directory are owned by foomatic-db-engine.

As for foomatic, I think it works something like this:
* The foomatic-db-engine package installs some sort of "driver interface" for CUPS that generates printer PPD files from XML. It also provides its own print spooler.
* The foomatic-db packages contains printer and driver information stored as XML. The package also contains pre-compiled PPD files for CUPS, so foomatic-db-engine is not requiered if you use CUPS.
* Some driver packages like hplip require foomatic-db-engine, maybe in order to generate some of the PPD files for CUPS (I don't know).

Looking at the gutenprint package:
* According to optional dependencies, both cups and foomatic-db-engine are supported spoolers, i.e. foomatic-db-engine is not required.
* The package contains XML files for both foomatic and gutenprint, but also pre-compiled PPD files for CUPS.

My guess is gutenprint shouldn't have to parse the XML because it provides its own PPD files for CUPS.
Problems arise when gutenprint is installed alongside both CUPS and foomatic-db-engine, because the foomatic-db-engine driver interface for CUPS will try to parse all the XML from gutenprint to generate PPD files.

herOldMan wrote:

I would be surprised if there was some sort of equivalent XML parsing in gutenprint, as gutenprint already contains gzipped PPDs, and AFAIK it does not try to implement a spooler system like foomatic-db-engine.

Even if you had foomatic-db (not -engine) installed, this package only contains XML for foomatic itself (not gutenprint), so it seems unlikely that gutenprint should have the same problem of trying to generate PPDs from it.

If foomatic-db-engine is not installed on your system, you are not experiencing the exact same problem as me (/usr/lib/cups/driver/foomatic).

If you remove the gutenprint XML schemas located under /usr/share/foomatic/db/source/.... (look at "pacman -Ql gutenprint"), I guess this should indeed stop foomatic-db-engine from wreaking havoc and just let CUPS use the pre-compiled PPD files provided by gutenprint. But again, with foomatic-db-engine not installed on your system, these XML files should not even be in use.

If you use "top" and press [c] to toggle full command display, which process(es) consume all the CPU during administrative tasks?

This sounds like a completely different bug - something like the stuff @mcloaked is onto.

I have a samsung ml2165w
The 100% cpu usage starts when I power off the printer... I have to stop or restart the service...

Testing the https://bbs.archlinux.org/viewtopic.php … 6#p1482856 changes now....

https://bugs.archlinux.org/task/42666
SOLUTION
to modify /etc/cups/client.conf
remove ServerName /run/cups/cups.sock and replace it with ServerName localhost:631

PD: it seems to work for me... printed a few pages, then powered it off... and no 100% cpu
PD2: no... it happened again today... lol

Hello all!
I had the same problem plus some after the last system upgrade. I managed to partially fix part of them but high cpu usage still persists plus the printer that used to work without a problem before the upgrade (Brother HL-2270DW, network) is not working anymore, usb hp printer is uneffected. I deleted the Brother printer, tried to reinstall it but cups could not find printer drivers although the standard ones with gutenprint and foomatic plus hl2280 from AUR were installed (I tried to reinstall it both manually and through web-interface). After playing with it for a few days, following all the advice I could find online I managed to re-install the printer but only as a usb one. When I modify it as a network (lpd or dnssd) with the same driver as for usb (hl2280) I get a message "unable to locate the printer".
As result of the last two days I don't have foomatic-db-engine.
Another thing that I found is

$ lpq
lpq: Unable to connect to server.
$ lpr /home/file.pdf 
lpr: Error - scheduler not responding.

I cannot print any files but the test page, and on web-interface it doesn't show that I even sent a file to print. When I tried to send a file to print from FireFox at first it was getting printer information for a few minutes and then FF crushed, now it doesn't show Brother printer available, I can only print to file from FF. Okular gives me the list of all printers, sends file to print but actually nothing happens, the job doesn't appear in the job list.

herOldMan · 2015-01-09 21:32:53

On the cpu, my client.conf has the fix applied, but I still get the high cpu on administrative tasks.

On the missing printer:

My cannon network printer went missing in a similar fashion. I then assigned it a static ip and changed my printer connection to:
lpd://<printerIP>/PASSTHRU

Not sure why the dnssd connection stopped working, but the work-around is fine by me.

Shim · 2015-01-10 18:00:04

I don't think I'm having only printer problems because of lpr and lpq messages, to me it looks like the issue with cups rather than a printer.

mcloaked · 2015-01-10 21:03:11

If anyone can add diagnostic data to the bug reports at https://bugs.archlinux.org/task/42666 and/or https://www.cups.org/str.php?L4521+P-1+S-2+C0+I0+E0+Q then it would likely gain more traction towards a fix than posting here.

silviosa · 2015-01-14 12:02:35

I have 2 archlinux boxes. One recently updated, the other not. The first box had the high cpu problem, the other not. Comparing installed package I found the only difference was cups-filters. So I rolled back to cups-filters-1.0.61-3-x86_64.pkg.tar.xz and I have no more high cpu in the first box.

Maybe the problem is caused by cups-filters-1.0.61-4-x86_64.pkg.tar.xz.

AndyRTR · 2015-01-15 20:10:53

cups-filters 1.0.61-4 was a simple .so rebuild against poppler 0.29.0 - this shouldn't cause any harm and any older version should give missing .so link error.

But for sure cups-filters could cause the load due to a different reason.

silviosa · 2015-01-16 12:46:19

Tks for your answer, AndyRTR.

I confirm I'm running cups-filters 1.0.61-3 without erros:

[srs@localhost ~]$ pacman -Qs |grep cups
local/cups 2.0.1-1
local/cups-filters 1.0.61-3
local/cups-pk-helper 0.2.5-1
local/libcups 2.0.1-1

But I'm sorry. The high cpu problem was not solved, but you can hardly notice it because, when you ask for finding printer, it comes immediately. One cpu is loaded up to 100% shared between System and User for 3 our 4 minutes. Using 1.0.61-4, my printer was never found and the cpu load goes up to 100% for more than 10 minutes.

Tks again, and if you feel I can be in any help, please, let me know. I can, for instance, build up a virtual machine for testing.

AndyRTR · 2015-01-16 15:56:25

Can somebody confirm if old cups-filters 1.0.61-3 solves all high load issues? Then this might be cause by miscompilation.

( I wonder how cups-filters can be involved when adding new printers - isn't the filters stuff only used when translating between the document and printer language? )

silviosa · 2015-01-19 12:02:30

I'm running cups-filters 1.0.62-1 now and having the same behavior as 1.0.61-3. That is:
- cups can find my printer, so it is fine.
- high cpu still occurs but for "only" 3-4 minutes on one of the cpus (i run a Core I5). This can't be noticed as the all system does not slow down.
I listed the files been accessed during the high cpu load, if it can be in any help. See bellow.

I thank you again for concerning about my post.

What solved this same issue for me was to remove the Foomatic drivers.

i just want to add that i too have been facing this issue for awhile. on both my arch laptop and my arch desktop.

i've tried all the recommendations here but still get 100% cpu usage if it has to find my printer or if i have to administrate it.

i can't even print. it gets stuck with cannot locate printer. tried via usb and ethernet. the prior cups version worked. cups has worked with this printer for three years.

right now i have to boot into my hackintosh hard drive on my desktop to print stuff. this is incredibly annoying.

i tried looking in the aur for the previous 1.x version of cups but don't see it. if someone still has all the libs including 32bit cups 1.x, could you upload it to the aur?

EDIT: Deleted irrelevant jabbering...

I'm also affected by this bug, and I kept looking around for a solution.
CPU load is at 100%, when adding or modifying printers.

EDIT2:
The CPU load hits the roof when cupsd loads the backends, which only happens when one modifies or adds a printer.
