I am often running out of memory on my VPS ubuntu server. I wish there was a way to simply restart apache2 when it starts running out of memory, as that seems to solve the problem. Or am I just too lazy to fix the problem? I do have limited memory on the server...

Okay, more information:

I'm running apache2 prefork, here are my memory settings (i've been tweaking them...):

StartServers         3
MinSpareServers      1
MaxSpareServers      5
MaxClients           150
MaxRequestsPerChild  1000

The VPS has 1 GB of ram, running ubuntu 11.04 32-bit.

As for scripts, I have a wordpress network with 5 blogs, an install of AskBot (a python/django stackexchange clone), and an install of MediaWiki that isn't really used. There is also a homebrewed mp3 script that accesses the getid3 library to display information on lists of podcasts, and it seems to be throwing some php errors, not sure if that's the culprit...
