ext3 assertion failure



Hi all,
I woke up this morning to find this on one of my machines. The machine is still
running but the load according to top is over 13 yet I see no processes actually
loading the machine. The only running process is top itself.
Below is hopefully the revelent output from dmesg and /var/log/messages. I 
have had this b4 but this is the first time I have been able to get any useful 
information from it.  The machine usually locks and all I see is the assertion 
failure on the console. This is a stock 7.2 system with all revelant updates.
FWIW this appears to have happened about the time the cron.daily stuff 
ran (logrotate updatedb etc). The machine has been up for approx 36 days.
Not sure what other info to provide so if I missed something please let me
know.

Can someone please tell me what this means?? Should this go in bugzilla?
