Description ptomblin 2006-09-27 18:22:21 EDT
Description of problem:
Since yum installed glibc 2.4-11 on the 16th of this month, my system has been
accumulating zombies at a horrific rate.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Use the system
2. Note the number of processes creeping up at a fairly fast clip.
Actual results:
Over 700 processes on my system, and increasing at a constant rate.

Expected results:
Approximately 200-250 processes on my system at any given time.

Additional info:
See the above munin graph showing the number of processes increasing.

I'm attaching the results of a "ps auwwfx".

An additional symptom: when I try to shutdown, I get the following:

shutdown: timeout opening/writing control channel /dev/initctl

init: timeout opening/writing control channel /dev/initctl

I had to hit the reset button to reboot.

Rebooting appears to have fixed the problem.  It appears that upgrading
something, probably glibc, without rebooting was the cause.
Comment 4 Jakub Jelinek 2006-09-30 03:23:48 EDT
Couldn't reproduce this on any of the 6 boxes I have upgraded FC5 glibc to.
If anything, it would be a kernel issue.
