I think the answer will come from analyzing your log files and possibly
running something under cron (or in a shell script that wakes up
periodically) to gather memory/resource utilization.  Even look at a web
log analyzer, like analog and see if there is a correlation between web
server hits and resource usage.  You could also try upgrading your web
server/plugins or checking bugzilla for related bugs.
