I had a bit of a chase this morning tracking down an issue on the new server (new server = ash, old server = tulip, old old server = elm.) CPU usage was being pegged at 99.9% by mysqld. Turns out - I think - to be a problem with some PHP code I had written (who would have guessed!) Anyway, I ended up learning a bunch about MySQL that I didn't know previously, so these things should be easy to track down in the future. For my own reference I will link here to this excellent Jeremy Zawodny post on tuning MySQL.
