dbus-daemon and gnome-vfs-daemon constantly restart

[Martin Emrich]

After adding two lines with NFS mounts to my /etc/fstab and saving, my CPU usage jumps to 100% with no apparent process consuming it. Upon watching the process list, I see two processes with their PIDs constantly increasing:

martin 12966 0.0 0.0 2764 340 ? R 18:30 0:00 dbus-daemon --fork --print-address 18 --print-pid 20 --session
martin 12967 0.0 0.1 8380 2724 ? R 18:30 0:00 /usr/lib/gnome-vfs-2.0/gnome-vfs-daemon

Their parent process is this one:

martin 5118 3.2 0.0 2764 1020 ? Rs 18:22 0:30 dbus-daemon --fork --print-address 18 --print-pid 20 --session

Here is an strace of a few seconds of the parent process.

While trying to post it to launchpad, my computer became more and more unresponsive, and I had to reboot.
After rebooting, the problem persists. Only after removing the NFS mounts from my fstab and rebooting again I can use my computer again.

Here are the NFS lines:
192.168.80.1:/home/martin /home/martin/serverhome nfs rw,user,noauto,async,soft,intr,nfsvers=3 0 0
192.168.80.1:/home/martin/files/media nfs /home/martin/files/media rw,user,noauto,async,soft,intr,nfsvers=3 0 0

I am running gutsy (installed from the Tribe 2 CD) i386, with current updates.

Thanks for your bug report. Please try to obtain a backtrace http://wiki.ubuntu.com/DebuggingProgramCrash and attach the file to the bug report. This will greatly help us in tracking down your problem.

I don't think I can attach to them fast enough, as they constantly re-spawn with different PIDs. For now, I tried to get an strace with this script:

#!/bin/bash
DBPIDS=`ps aux | grep dbus-daemon | grep martin | grep -v grep | cut -b 10-15 | xargs echo`
VFSPIDS=`ps aux | grep gnome-vfs-daemon | grep martin | grep -v grep | cut -b 10-15 | xargs echo`
STRACE_ARGS=`echo $DBPIDS $VFSPIDS | perl -e '$x = <>; @p=split(/ +/,$x); print join(" -p ",@p);'`
strace -p $STRACE_ARGS -o ~/bug128024-gnome-vfs-daemon+dbus-daemon-trace.txt

I started it (tracing all dbus-daemon or gnome-vfs-daemon processes belonging to me, an a second later, I saved my fstab with the NFS entries. A few seconds later, I ended the trace.

BTW: If one of them would SEGV, shouldn't apport be popping up? Or works apport only for specific processes?

Ciao

unconfirming, I don't get the issue and the bug doesn't look like a priority since there is no other bugs opened about it yet, maybe somebody else can work on it

[Pedro Villavicencio (pedro)]

Are you still getting this problem?

[Martin Emrich (emme)]

Yes, it's still there. My current workaround is to mount my NFS shares from the command line, but I hope this gets fixed for gutsy.

Ciao

I tried once again to see if it is fixed, but it is still there. Today I had the Idea of running dbus-monitor.
Attached is the output of ca. 3-4 seconds dbus-monitor, after enabling the lines in fstab.

Ciao

I tried once again (in hardy) and now it is fixed. As nobody else complained about this in gutsy, I'd recommend to mark the bug as invalid now.

closing the bug

[Sebastien Bacher (seb128)]

thank you for the update, feel free to reopen if you get the issue again on hardy
