The production server we are trying to run on only has 128mb of memory. I can't believe we got a machine with that little, but it happened. I might try running only 2 children of SPAMD, refreshing the processes every 5 messages or so to see if that will work, but I'd say the machine is a little light on the horsepower.
Glad to hear that you found the problem. I do not know about horsepower, but 128Mb of memory sounds hopeless or at least very limiting:>
