What version of code are you running? Can you get a "show tech-support"
off the router next time it freezes up before you reload it?
You might check to see if the interface's input or output queues are
full when this happens. Actually before it happens you might check to
see if the queues seem to have packets "hung" in them. I've seen a few
bugs in the past that would cause packets to remain in the queue and
after the queue was full it could not send or receive data depending on
if it was an input or output queue issue.

This network is in production.
I am sure some of you had the same situation before. I just want to know
anything that you may know.
