Server Crashing/High Loads

[HSAdam]

Hey guys,

I'm having a huge problem with one of my servers crashing/lagging majorly due to high loads.

I have been trying to figure out the cause of this for the past week and thought I had it fixed but I guess I do not.

For some reason the load keeps spiking for no reason, I do top and there is nothing there that would cause this, nothing is using alot of CPU/RAM.

This server has 1GB RAM total and I had it replaced incase the RAM was bad.

I also checked the error logs and could not see anything wrong..

Can somebody please help me out here? This is getting very confusing...

Regards,

I found the problem - a user was recieving TONS of email, the mail queue was 4k+, but the thing is the user recieivng, and the guy sending, are both _not_ on the server..

What can be done to fix this???

you can block the ip of the server sending mails through you server.
