Just found out last night my server has crashed, what was the cause?  My root partition, which had a ext4 filesystem, somehow corrupted on me.  What made it corrupt is still unknown, yes I am investigating it...  Recovery is underway, but may end up having to redo the partition. 

I went with ext4 do to speed advantages over ext3, but I never had a problem like this before with ext3.  A filesystem like jfs is starting to look good right about now.

On a lighter side I just got a complement on my Nexus One.
