Downtime

MySQL fell over at around 9am GMT and was down until around 1pm GMT (I woke up at 7am Canadian time ). I did some optimisations to the MySQL daemon that may have been a little over-optimistic, it caused the server to eat all it's memory and kill the MySQL process.

I've changed the settings so MySQL won't munch quite so much memory, there may be some more downtime today or tomorrow if my changes weren't enough. Sorry for the inconvenience!
