FC3 kernel panic: <0>kernel panic-not syncing:fatal exception in interrupt

Hi,

I install FC3,and running about 20 days, get kernel panic.
This server serves mult-threads program(about 100 concurrent threads), I/O is heavy.

Below is the message leaving on screen:

   <0>kernel panic-not syncing:fatal exception in interrupt

Any suggestions are welcome.
