I'm pretty confused. We have an Apache-served RT 3.8.7 instance with Postgres backend. It's using mod_perl. All 10 current httpd processes are over *300MB* each already after a host reboot 30 hours ago.
We have a NON-RT system, with the same OS and package versions, serving 10 times more people via mod_php + Postgres (a SourceForge-like system). All current httpd processes are ~50MB after being up for 5 days. What gives? Any ideas?
