I already had maximumThreads set at 50 (sorry I didn't mention that, there's 
so many configuration variables that I have fiddled with trying to tune this 
thing that I forget what I've done to what!). When Frost overloaded my node, 
it had *HUNDREDS* of threads open, though. How could that be?! (My node is 
running Mandrake 9.0 Linux, stock 2.4.19 kernel). 

I will add the defaultResetProbability line and see if that helps. Thanks,

maxConnections is ignored. maximumThreads is the relevant parameter.
Try:

maximumThreads=60
defaultResetProbability=0.01
