I am having issues with one of my apache servers. Sometimes, it takes a really long time to load a page. For instance, ssh'd into the machine I do a wget for a page on that machine. It can take up to twelve seconds for the page to load. I have checked the memory and cpu and neither seem to be higher than normal.

The frustrating part is that five minutes later I can check it the same way and it will load instantly.

Can someone help me troubleshoot this? Thanks!

---> UPDATE

I have determined that it is actually not apache, but the php module that is really slow. I tested this by trying to wget a html page instead of a php page when things were slow. The php page hung for a while but the html page downloaded right away.

Still need help though.

--> UPDATE

we ended up just restarting apache after php starting giving out the same session id to multiple people. This was allowing people to read other peoples mail. I guess no more need to troubleshoot.
