hmmm. I've now been monitoring the okfn.org server for a couple of weeks 
and loads are getting very high. Frequently I have seen it in the 5-30 
range and I've seen it as high as 80 (at that point the server is 
essentially dead). The problem seems to lie with apache (the main way 
I've been solving the problem is to stop/start or restart apache).

However I've had difficult working out exactly what the problem is. I 
thought it might be to do with a memory leak in modpython stuff related 
to knowledgeforge and therefore have tried upgrading modpython. I only 
did this a few days ago so it is difficult to know how much impact this 
is having yet. Alternatively it may just be that the machine is getting 
too much traffic.

If there's anyone out there with suggestions or experience of tracking 
down these kinds of problems let me know (I'd also like to know why, for 
example, htop and top produce such different process lists ...). I've 
got a load of top logs and other system stats which I can post on the 
sysadmin wiki if that would help
