"ps v -C <server-process-name>" will tell you how badly you're hurting Anybody that does a bunch of lookups -- whether this is forward lookups for customers or blacklist lookups on mail or whatever -- is probably using more than they think. I don't know of many directly related crash scenarios but there are other penalties like shallow caching which aren't entirely trivial. The churning strategy employed is the question that doesn't get answered. Some servers do FIFO, some do random discards, some use swap space...
