Interrupt using all the CPU

[nocturnal]

Hi

I'm having a few problems with a webserver. Today the idle was at 0.0 
and it's still like this. It doesn't look like it's affecting web 
services but it looks weird and i'm afraid that the CPU is working it's 
ass off with something. Of course nothing shows up in top or ps that 
could indicate which process is taking up all this cpu and since 
interrupt is the one using it i'm not even sure anything is actually 
using up CPU since i don't know what interrupt is. Any hints or pointers 
would be appreciated.

It looks like interrupt and system are fighting for percents, interrupt 
has 100% constantly and as soon as interrupt drops system takes exactly 
what's left over and sometimes system doesn't do it so idle gets a few 
percents. It's weird to me simply because i can't find a description of 
what interrupt shows in top anywhere in the manuals.
