unkillable totem process

[Robin Sheat]

Binary package hint: totem

I have a totem process that can't be killed:

robin@dagobert:~$ ps ax|grep 27714
27714 ? Dl 6:49 totem file:///home/robin/Download/torrent/done/%5BDB%5D_Bleach_151_%5BE3DC6A4C%5D.avi
27974 pts/0 R+ 0:00 grep 27714
robin@dagobert:~$ kill -9 27714
robin@dagobert:~$ ps ax|grep 27714
27714 ? Dl 6:53 totem file:///home/robin/Download/torrent/done/%5BDB%5D_Bleach_151_%5BE3DC6A4C%5D.avi
27977 pts/0 R+ 0:00 grep 27714

Note how the CPU time is increasing also: it's using 100% of one of the CPUs. There is no window open for this (it was being used, it finished, so I closed it, and the process remained behind using the CPU). The parent process is 'init', which obviously I can't kill. I own the process, and regardless, a 'sudo kill' makes no difference.

Oh, according to 'top' most of the CPU time is spent in 'sys', so perhaps it's a kernel issue...?

OK, likely not a totem issue:

...looks like it's stuck on the disk.

robin@dagobert:/proc/27714$ cat wchan
exit_mm

Going to reboot to make it get unstuck.

Thanks for the bug report. This particular bug has already been reported, but feel free to report any other bugs you find.

[Robin Sheat (eythian)]

This exact same thing happened again. Where was it previously reported so I can watch that bug? Rebooting to unstick a process is a bit annoying.

[Stéphane Marguet (stemp)]

Same problem here
pkill -KILL totem doesn't help
