With 34 children and only 1GB of ram? Yea, I think that might be the problem. Even with nothing else using memory, that only gives you 30MB per spamd child. My smallest spamd child is using 45MB at the moment. I would suggest adjusting your max children until you find a level that runs well without becoming overloaded. Try setting a max of 20-25 and see what happens. If it runs well, bump it up a bit. If it still has problems, drop it some more. -- Bowie
