Thanks for the tip!

Yes I do have my own caching nameserver running but as soon as I set the 
number of processes higher than 2 I start getting SA timeouts. With only 2 
I don't get any timeouts and everything is filtered as it should.

I don't know why SA is so slow. Whenever there has been an outage and 
there are several thousands of messages waiting SA seems to take hours to 
process one batch of let's say 30 messages or so.

I have the same behaviour on an almost identical box, frustrating.....
