[Bug 417778] Re: xfce4-volumed takes 100% cpu when system is idle for some time

[Chris Moore]

I left my laptop on overnight.  Usually it's very quiet, but I just
noticed the fan was running loud.  I checked with 'top' and saw that one
of the CPU cores was pegged at 100% CPU.  The xfce4-volumed process was
responsible.

gdb shows me:

(gdb) where
#0  0xb78c5430 in __kernel_vsyscall ()
#1  0xb75e6ba6 in poll () from /lib/tls/i686/cmov/libc.so.6
#2  0xb783c53b in g_poll () from /lib/libglib-2.0.so.0
#3  0xb782f55b in ?? () from /lib/libglib-2.0.so.0
#4  0xb782fb8f in g_main_loop_run () from /lib/libglib-2.0.so.0
#5  0x08049fb2 in ?? ()
#6  0xb753eb56 in __libc_start_main () from /lib/tls/i686/cmov/libc.so.6
#7  0x08049c91 in ?? ()

and strace refused to attach:

chris at chris-laptop:~$ sudo strace -p 2541
[sudo] password for chris: 
attach: ptrace(PTRACE_ATTACH, ...): Operation not permitted

so this is still a problem.

I often leave the machine idle, and have only seen this behaviour once
before.

This is on an up-to-date karmic box.
