browsers 100% cpu and a black helicopter

For about a month I have had a severe problem with firefox and other browsers burning CPU. These are the ones that are OK:
opera        7.5.4
dillo          0.8.4
These run the CPU up to 100% and it stays there:
firefox      1.0
mozilla     1.7.5
galleon     1.3.19
epiphany  1.4.7
This happens with a fresh install of any of these browsers, with any user, even root.

Today I decided to install wombat base on a spare partition, and dropped in the latest firefox from my local arch mirror. All worked as it should. Then I switched back over to my old install, which is also Wombat via pacman. The CPU problems have simply gone away. So my question is DUH?? There was no way I could fix this before, I reinstalled java and other things but it made no difference. Worse, even though the CPU was burning hot, nothing showed up on top as using CPU.. All I got was total cpu, ( i.e. sys + user )  = 100 %. Nothing showed up on ps ax either, just the browser binary.
I suspected I had been r00t3d, but nothing shows on the rootkit tools.
I did not install grub today, I just edited my old menu.lst.
One strange thing did happen after I returned to my old system. I was running a script to download some files with wget, playing some music with xmms, and doing a locate *|grep -i richard, to find all the Little Richard music I have. It started to get unresponsive, with 384M of ram, that is unexpected. It was heavily into swap, so I did a swapoff -a; swapon -a, and the problem went away. xmms died. So there was the source of that problem.  I restarted xmms, and away we go. Now I have all of those browsers open, alive and kicking, wget has not stopped, and we have just 20% CPU peak and 0% or so min.

So what was it? and Why did it go away? And when will it come back?
OH, yes the problem was there immediately before I installed Wombat.

Re: browsers 100% cpu and a black helicopter

please try to start firefox and go to "about:config"
and there is a option
network.dns.disableIPv6
and set it to true...

Re: browsers 100% cpu and a black helicopter

Thanks. That might fix the fox, but right now I am using epiphany, and there is no ipv6 setting in the config that I can see. I guessed libgtk2 or mozilla-core being destroyed by a website. But how could an install on another partition fix this? Maybe it is a coincidence. Anyway I will change the ipv6 settings and see what happens. Yep. got the lot. Today I will get some reading glasses.
Another diff is that xfce4.2 was s.l.o.w now it is quicker, but still not the way it should be. e.g. opening 4 xfterm4s on one page brings up the menu and you have to move your mouse off the icon & back & wait for it to ungrey. It is better than that on the new install.

Re: browsers 100% cpu and a black helicopter

it makes no difference for me when ipv6 disabled. mozilla 1.7.5 still charges my cpu at 100% during tabbed browsing or using java.
by the way, i never observed this kind of problems with mozilla 1.7.3  roll

Re: browsers 100% cpu and a black helicopter

Interesting... The problematic ones are all Gecko-based. Now if we had GTK-Webcore in Unstable, you could test that and see if it caused problems...

I haven't a clue how to solve this thing though. Mozilla can be a RAM hog, and I've seen Firefox display memory leakage under certain conditions... But I've never seen either program use much CPU time.

Black helicopters?  Reading glasses?  Man, you're my kind of poster.  That's some funny shiznitt.  I really don't have an anwer to your problem, except for one...instead of the reading glasses, do like me and duct tape a pair of binoculars to your head.  It makes for easier monitor viewing, plus I was able to peer out my window and make out Donald Trump's face in the helicopter.  I don't know what he's up to, but the tin foil lining my walls should keep me safe for the moment.

Re: browsers 100% cpu and a black helicopter

are we alone with this kind of problems?

i think there's really something fishy with java.

i tried 3 different versions of mozilla and the recent version of firefox with the last 3 versions of j2re before i made a new installation from cd (arch-0.7) and the first thing i tested was running a java applet. always the same bug - even after a system update!

tranx     3922  0.0  0.5   4812  1380 pts/0    S+   02:03   0:00 /bin/sh /opt/mozilla/lib/mozilla-1.7.5/run-mozilla.sh /opt/mozilla/lib/mozilla-1.7.5/mozilla-bin
tranx     3927  4.4 12.3  97440 31416 pts/0    Sl+  02:03   0:12 /opt/mozilla/lib/mozilla-1.7.5/mozilla-bin
tranx     3934 35.1  9.4 273804 24088 pts/0    Sl+  02:04   1:28 java_vm

the applet begins to initiate but refuses to charge, apart from my cpu  :?

Re: browsers 100% cpu and a black helicopter

ok, i eventually found a solution: go and open your browser (in this case mozilla)

edit - preferences - advanced - AND DISABLE JAVA!

java/Firefox is for losers anyway.  Lynx is for 'studs'...

Re: browsers 100% cpu and a black helicopter

Apparently 1.5.0 update 2 fixes this issue, but it's not on the Arch repos yet...
There are quite a few things half-broken in update 1, eg can you run javaws normally under Linux?

He didn't say X is for losers... gLinks is quite capable of displaying graphics.

Re: browsers 100% cpu and a black helicopter

FYI 1.5.0 update 2 does not work either (with Firefox 1.0.2)...
I tried it on an Ubuntu Hoary laptop, and the stupid java animation screen keeps spinning forever (not hanging and 100% CPU though, which is an "improvement"...).
Konqueror works OK (IMO a bit slow handling java applets, but it does work).
