Has anyone here a idea whats wrong with this machine:

This box has usually only 2-30MB of 256MB free. I notice there are alot Apache sleeping processes. Is that normal?

Thanks,

Best solution just reboot the box :)

Yes, reboot and consider adding more RAM. Anytime you use your swap file, that dramatically slows down the proesses that use it. Your sever has been up for 30 days and you have UBB running as well. That can be a resource hog. Rebooting will recover some of your memory for usage.

That machine isn't running out of RAM.

That's the RAM available after the OS allocates most of free RAM to the disk cache. If you end up needing more RAM, disk cache is de-allocated so it can be used as system RAM.

The number on the line below is the true amount of free RAM.

You don't seem to be running out of ram. Those stats are normal. I have 512 megs on one of my servers and it almost always shows %80-%90 usage. Monitor your swap file to determine whether or not you need more ram.

Thanks :)
