Hello everyone,

I'm a complete rookie when it comes to all things Linux related so please treat me as such and assume I know nothing. That being said my Top says this:

And my hard drives says:

none                   4088440         0   4088440   0% /dev/shm

It has been like it for a few days now...

I know not what is causing the high server load (Normally around 1.3) can anyone give any tips on how to track down the culprit?

Many thanks,
