Hi,
I'm trying to track down an issue I have with our apache server. Its a poweredge 1800, RHEL5x64 server, running httpd-2.2.3-22.el5. Its mainly used as a subversion repository, via HTTPS with LDAP lookup for authentication. All was well with the system, running 1Gb of ram, until I did a yum update, and also upgraded subversion from 1.4 to 1.5. Since then, apache consumes vast amounts of RAM, with very little user interaction. We've upped the memory to 12Gb of RAM, but even that gets consumed within a few hours. Obviously something is eating the ram. So my questions are: 1) How do I find which module it is in apache thats consuming the ram? (I'm 99% sure its subversion, but need evidence) 2) The apache docs talk about it having its own memory management, but what config options are these, and how (roughly) should I be setting them? 3) When the memory is consumed by httpd, and I stop the httpd process, it quite often doesnt return the memory to the OS, leaving 11Gb in "limbo" somewhere. Is there a way to reclaim this ? Thanks Adrian Marsh
