Ok, So I've switched to the collab.net version of the subversion package. This includes a 2.2.8 version of apache. They also only include 3 modules I their config (python_module, dav_svn_module, authz_svn_module). This seems to be enough to get SSL and LDAP lookups working for me. After around 30mins of running, memory footprint is: 22876 csvn 15 0 119m 17m 3492 S 0.0 0.1 0:02.21 httpd 22875 csvn 15 0 114m 12m 3564 S 0.0 0.1 0:01.08 httpd 22874 csvn 15 0 112m 11m 3588 S 0.0 0.1 0:00.79 httpd 23041 csvn 15 0 113m 10m 3052 S 0.0 0.1 0:02.32 httpd 22886 csvn 15 0 113m 10m 3544 S 0.0 0.1 0:00.77 httpd 23043 csvn 15 0 113m 10m 2976 S 0.0 0.1 0:00.51 httpd 22873 csvn 15 0 111m 9.9m 3588 S 0.0 0.1 0:01.03 httpd 22877 csvn 15 0 111m 9.9m 3548 S 0.0 0.1 0:00.44 httpd 22885 csvn 15 0 109m 8368 3444 S 0.0 0.1 0:00.44 httpd 23042 csvn 15 0 109m 8088 3464 S 0.0 0.1 0:00.23 httpd 22872 csvn 18 0 53780 2720 1004 S 0.0 0.0 0:00.00 httpd So each httpd process started with approx 3-5Mb each, and have grown to say 17Mb. Certainly better than my previous setup. I'll monitor over the next week and see if it stays at that level.

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.
