I bet the swap partition bug struck again.
We really must get this fixed at all costs, admins. I'll check the logs tonight. What if I put back the default kernel ? I don't see why mine would cause the problem, though, but better make sure... No time for that right now, but in the meanwhile if memed or Nova want to take a look, please guys, do !
And to all members... we are sorry

The server crashed just at the beginning of the weekend and the hosting company was closed and nobody could reboot it until this morning

We'll be investigating the issue ASAP. Hopefully this won't happen ever again.
