Description of problem:
After upgrading our kickstart RPMs to include the new kernel errata rpm (kernel-2.4.18-17.7.x), we are seeing the following error when restarting httpd on boxes kicked with this config:
[Wed Nov 20 16:37:19 2002] [error] mod_ssl: Cannot allocate shared memory: mm:core: failed to acquire semaphore (No space left on device)

Perhaps this is related to bug 78019.  Seems similar but not exactly.  It appears that some process is leaking sempahores.

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

How reproducible:

Steps to Reproduce:
1. Kick system with kernel-2.4.18-17.7.x, apache, apache-1.3.22-7, mod_ssl-2.8.5-6, php-4.1.2-7.2.6, postgresql-7.2.1-5
2. Use sqlrelay (from to broker php's database requests
3. Allow httpd server to run for a while and service many PHP database releated requests (suggest using siege or something similar to inflate the number of requests quickly)
4. Restart apache via apachectl restart

Actual Results:  The system appears to be out of sempahores for some reason and yields the following error in the apache error_log:

[Wed Nov 20 16:37:19 2002] [error] mod_ssl: Cannot allocate shared memory: mm:core: failed to acquire semaphore (No space left on device)

Expected Results:  Apache gracefully restarts.

Additional info:

If I can find a way to 100% reproduce the problem I will update the bug later this week or next.  Thanks for any light shed on the problem.

This was probably the mm bug, and should have been fixed by:
