Hello!
I got oops after about 3 hours of uptime. Load was about 1,5.
This is output of ksymoops after forced reboot if it helps someone. :-)

We used a data structure after it was freed. That is exceedingly bad. It's also very unusual - thousands of people have used this code for months without achieving what you have :) Do you think there's anything unusual in your usage? Any peculiar workload or hardware config? It's a uniprocessor? Are you confident that the hardware is good?
