Can anyone offer any advice on how to tune a windows / apache / postgresql
system? Our setup is regularly experiencing problems with moodle's memory
usage mounting to over 1,000,000 k, and the system stalls. Restarting the
server is the only way to get it going again. Moodle is running on a dual
Xeon 2.00 ghz processor with 4Gb RAM, and we recently moved the database to
a separate server with a similar spec. This has not improved the situation -
if anything it is worse.
We are running Apache 2.2.10, PHP 5.2.6, Moodle 1.8.7, PostgreSQL 8.2. We
had similar problems a few months ago, which I thought was due to the known
Windows "memory leak" which occurs with certain combinations of apache / php
versions. Upgrading to out currentversions of Apache / PHP did show
considerable improvement but now it is happening again (maybe because the
number of users has increased?).
I have autovacuum set to on for postgres, but don't do any other regular
vacuuming. Should I?
Any suggestions gratefully received.
