Red Hat Bugzilla – Bug 834715
yum ps plugin shows unknown an process
Last modified: 2014-01-21 18:22:50 EST
Description of problem:
When executing 'sudo yum ps', a line that contains:
19887 <Unknown> 0:00 0 B Unknown: *15513 day(s) 20:56:35
appears once for every package. The system uptime is 13 hours and no package has been updated in that time. There's no running process that owns this PID.
Version-Release number of selected component (if applicable):
Unknown. It may be solved with a system reboot.
The unknown process should not be displayed

This system was rebooted after this update.
Hi, could you run "ps -F -p 19887" when this happens again? This might be related to bug 745281 (get_process_info failed). yum-3.4.3-28.fc17 should show more information in such case.
I had to reboot the computer, but this bug still seems to happen. The unknown process ID is now 11999. Running:
$ ps -F -p 11999
UID PID PPID C SZ RSS PSR STIME TTY TIME CMD
Exit code: 1
Update: I tired to launch Python (as a regular user) and do:
import yum.misc as misc
Doing so returned a list which did not contain the ID of the unknown process. Afterwards I tried to launch 'sudo yum ps' again, but no process was displayed this time. I'll update as soon as the bug happens again.
I'd guess at weird kernel problem, but who knows.
