[Sambonim]

Hello,

We are having issues with one of our servers, apache stops 3 times per week, we have on this moment Fedora 5, with Intel(R) Xeon(R)CPU 3050 @ 2.13GHz and 4 GB of memory, we have 300 domains on this server.

The firewall it's active, and the following ports blocked for remote access:
MySQL; PostgreSQL; Tomcat; Samba; Plesk VPN

As you can see apache it's getting to many memory, Plesk 8.2
Any one have tips for this problem?

Thank you.

I suppose 200mb of RAM is not that much for 300 of domains running, esp. with 4Gb RAM total.
Re Apache stops, if it restarts after stops automatically, then it can be normal:

But if it stops and then fails, then likely this is a case of the piped logs and file decriptors, please:

Especially if its 64-bit, or you have a lot of modules loaded (ioncube, sitebuilder, zend, etc)
