Our database server crashed last night. We recently moved to the new server and like an idiot I forgot to apply one of the latest patches. I guess in RedHat 7.3 on SMP servers with EXT-3 filesystem the kernel could panic under certain circumstances. Well last night around 2am was one of those circumstances. It's all good now. We upgraded the kernel and no data was lost. We will be keeping an extra close on eye on things for a while to make sure we are stable.
