Subject: [rt-users] RT memory usage


Dear list, we are running RT on a xen virtual machine running Debian
etch (4.0), Linux rt.outernet 2.6.18-4-xen-686 #1 SMP Thu May 10
03:24:35 UTC 2007 i686 GNU/Linux

the VM had 256M RAM and a default apache installation. Versions of
apache and RT packages:
ii apache2                2.2.3-4+etch4  Next generation, scalable,
extendable web server
ii  apache2-mpm-worker     2.2.3-4+etch4  High speed threaded model for
Apache HTTPD 2.1
ii  apache2-utils          2.2.3-4+etch4  utility programs for
webservers
ii  apache2.2-common       2.2.3-4+etch4  Next generation, scalable,
extendable web server
ii  rt3.6-apache2  3.6.4-1        Apache 2 specific files for
request-tracker3
ii  rt3.6-clients  3.6.4-1        Mail gateway and command-line ii 


Because of out of memory problems we:
* increased memory to 512M
* limited the number of apache processes to 3 (including the root-owned
process)
* ran apt-get upgrade libdbix-searchbuilder-perl (it went from 1.49 to
1.53)

Now, after a reboot, 320 MB is free. After a couple of small browsing
sessions free memory stabilizes around 130 MB. One day later it is still
80 MB, but I have a feeling where this is going.

Are there more suggestions you can give me to make RT / apache2 eating
all the memory?

Regards,
Karel
