Should be fixed soon. I'm fairly certain this is the same issue as
mentioned earlier. For some reason ext3 inodes fill up the entire ram,
then the vm struggles trying to do an order 1 allocation (2 contiguous
4KB pages).
This was pretty much the same failure mode I saw when updatedb blew up
my box, except it was the e100 driver complaining for the same reason
(no memory).
