What load balancing software do you use ?
holygoat: I like Pound very much: it's simple and robust.However, I recently noticed a memory leak. We use healthchecks on our production machines, which means a consistent rate of hits every few seconds, 24/7. After about 3 months, Pound had chewed up 1.7GB of RAM, which caused memory usage alerts in our monitors.Not a big deal -- you can always restart the process -- but I'm still evaluating alternatives.
