Two wild guesses:

1. Your state table is filling up. Whats the output of "ipfstat -s" when the
   machine freezes?

2. if you are logging everything you block, maybe ipmon is eating all your
   cpu or the machine is busy doing heavy I/O. try ps, top, vmstat and friends
   to find out if that is the case.
