I run a fairly large phpbb forum and for some reason apache is failing every 10 minutes or so. My server setup is rather good in my opinion, it's a cluster running two duel xeon machines with 1 GB ram each. Server load rarely gets over 1.0 and I don't think I have ever seen it above 2.0 at all. It runs on a 20mbps line and never slows down.
The thing is apache still fails about every ten minutes.

The error log shows nothing, no error message as to why apache would be failing at all.
/var/log/messages is the same way, shows nothing odd.
max clients seems to have no effect, I do reach it sometimes but even after uping it past 250 I get the same result. Thats after raising the hard server limit also.
So if anyone has any ideas what would be causing this can you throw them my way, I'm at atotal lose here =/
