Thanks guys for the help so far... Lets just pretend for a moment that I don't know much about Apache, pthreads or pre-forks in any specific detail... how would I find out what threading model is being used? Ulimit does return 10240 on the command line. Should I put the ulimit -s 2048 into the init.d script for httpd ? As a side project, I'm trying to get my basic SSL and LDAP config working in Collab.nets version of subversion, which includes an apache binary custom for them I believe. I think I almost have that working, so I plan to switch the system over to that, and see if the problem still occurs. If it does, then I may have an official support route to follow.

The wasted stack space doesn't shows up as a high VSZ, but not RSS. -- Eric Covener covener@xxxxxxxxx --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
