Hello. A client of our company has similar issues. They run SLES 10 with apache 2.2.x and the newest subversion 1.5.x and also use https. For authentication they use winbind and not ldap. They too have the problem, that the apache processes take up a lot of cpu cycles and use up the ram to the point, where the processes crash with out ouf memory. After that the memory is not freed. Even when the httpd processes are stopped (and not crash) the memory is not freed. I do not know the fine details here, bit the sysadmin found some odd things going on with ssl. -----Ursprüngliche Nachricht----- Von: Tom Evans [mailto:tevans.uk@xxxxxxxxxxxxxx] Gesendet: Freitag, 3.

No its definitely the httpd process. I see each thread consuming hundreds of megs of RES memory being used in TOP. I just restarted it and already each is consuming: > > 10006 apache 15 0 279m 15m 3160 S 0.0 0.1 0:00.29 httpd > 10004 apache 15 0 278m 13m 3400 S 0.0 0.1 0:00.05 httpd > 10007 apache 15 0 278m 13m 3048 S 0.0 0.1 0:00.04 httpd > 10001 apache 15 0 277m 13m 3456 S 0.0 0.1 0:00.08 httpd > 10003 apache 15 0 277m 13m 2976 S 0.0 0.1 0:00.10 httpd > 10002 apache 15 0 277m 13m 3112 S 0.0 0.1 0:00.07 httpd > 10005 apache 15 0 277m 13m 3080 S 0.0 0.1 0:00.06 httpd > 10000 apache 15 0 277m 12m 3432 S 0.0 0.1 0:00.51 httpd > > Also, I forgot to mention its 1.5.5 of SVN (1.5.2 had a mod_ bugfix for a memory leak). > > What interests me at the moment is diagnosing which module it is (as others running 1.5.5 don't report this issue).

That 27[789]m reported as SIZE is shared between the processes, shared pages and the like, and the RES isn't excessive in my opinion. What does mod_status and mod_server_info say is going on when you notice the memory starvation? What precisely did you change with your yum update? Did that change core packages, like libc etc?
