Description Andre Robatino 2007-01-17 11:05:26 UTC
Description of problem:
  At about 5 AM local time, I noticed yum-updatesd sucking up all the available
CPU without letup.  I'm guessing this started about 4:02 AM when the daily
chores get done, but can't be sure.  I tried unsuccessfully to kill it with
signals 15 and 2, and finally had to use 9.

Version-Release number of selected component (if applicable):
yum-updatesd-3.0.3-1.fc6 along with all other current updates

How reproducible:
don't know

Steps to Reproduce:
1.  Not sure, may happen after 4:02 AM?  If so then wait.
  
Actual results:
yum-updatesd sucks up 90+% of the CPU continuously without letup.  Must be
killed with signal 9 (or maybe something other than 15 or 2 that I didn't try).

Expected results:
yum-updatesd using reasonable resources.

  It happened again - this time I noticed it at about 3:30 AM.

  Attaching to it with strace seems to indicate that it's not making any system
calls.

[root@localhost ~]# strace -p 2715
Process 2715 attached - interrupt to quit
Process 2715 detached
[root@localhost ~]#

(waited 10 or 20 seconds)

Comment 3 Andre Robatino 2007-01-27 02:00:13 UTC
  Shortly before the problem started, yum crashed with a segfault, and I had to
delete the __db* files in /var/lib/rpm to straighten out the RPM database.  But
after about 2 days it never happened again.  Closing.
