[Solved] pcmanfm eats up one core

Hi

Unfortunately I can't tell exactly since when this happens.

When I start pcmanfm it immediately uses 99+% of a CPU core, w/o doing anything! (Well, I assume it's doing something but I can't see what...)

This happens on my desktop and laptop.

Before writing a bug report, can someone replicate this ?

I tried downgrading some of the packages pcmanfm (gtk2) depends on but w/o effect... (Don't think that I've to reboot for this ?)
Any idea how to debug this ?

Re: [Solved] pcmanfm eats up one core

I have had the same problem for a couple weeks now on my Arch box.  On my Fedora box, pcmanfm still works fine.

Re: [Solved] pcmanfm eats up one core

Ok
It's a problem with my fstab.
When commenting out the removable devices pcmanfm works normally...

#
# /etc/fstab: static file system information
#
# <file system> <dir>   <type>  <options>       <dump>  <pass>
#tmpfs          /tmp    tmpfs   nodev,nosuid    0       0
LABEL=BOOT /boot ext3 defaults 0 1
LABEL=HOME /home ext3 defaults 0 1
LABEL=ROOT / ext3 defaults 0 1
LABEL=ROOT-HOME /root ext3 defaults 0 1
LABEL=SWAP-1 swap swap defaults 0 0
none    /sys/kernel/debug       debugfs defaults 0 0

#UUID=4647-5DB7 /home/cem/MOUNT-IPOD auto noauto,user 0 0
#/dev/sdd1      /home/cem/MOUNT-NATEL auto noauto,user 0 0
#UUID=5D49-3BCA /home/cem/MOUNT-STICK auto noauto,user 0 0

#amd64box:/home/cem /home/cem/NFS-MOUNT nfs noauto,user 0 0

I'll have to see what I can do about that...

I've the same problem too. The only solution I've find is install gvfs

Re: [Solved] pcmanfm eats up one core

I've had a similar problem with pcmanfm for the last couple of weeks. I have gvfs installed and my fstab does NOT contain any mountable devices. Most of time pcmanfm behaves as it always did. Now a cpu loop starts when I use the unmount icon in pcmanfm. If i umount the drive in a terminal it's OK, the drive disappears in pcmanfm and it does not chew all the cpu time up.

Once pcmanfm goes loopy closing its window does not help, again in a terminal a big 'killall -KILL pcmanfm' is required to stop the loop.

rebootl, if you can replicate this it's worth creating a bug report.

Re: [Solved] pcmanfm eats up one core

I mount my external disks and dvd readers with fstab. In fact I'd never used gvfs before (I don't need a Trash file and lots of gnome dependencies, last time I installed it) . Like rebootl says, when I comment out the external dvd  readers (not the external disks) pcmanfm fails

Re: [Solved] pcmanfm eats up one core

Thanks for the replies.

Edit: Since some have similar/same problems, I'll write a bug report.

I believe installing gvfs could solve the problem but the hole point for me in using pcmanfm, instead of another file manager, is to avoid these deps...

Edit: I was a bit too fast before. I found that disabling the auto-mount options in the preferences solves the problem! Since I don't need them that's fine for me.

Regards

Re: [Solved] pcmanfm eats up one core

When I go to pcmanfm preferences, then to volume management, then uncheck all 3 of the automount boxes (i.e. turn off automount), I still get 50% cpu use after I use the file manager a bit.  And the system then stays in that condition.

Re: [Solved] pcmanfm eats up one core

Now pcman is working properly since I've added gvfs.  For some reason pcmanfm was doing fine without gvfs until recently.
