 Hi,
     Do you have a backtrace for the issue (bt from ddb, or the
 equivalent bt from kgdb)? I'm asking because I saw various issues
 running with in kernel nat as well in various bits of the kernel --
 one was the ip routing code, one was the ipfw_nat code, and the other
 was the network driver that I was using, bce(4). All items suggested
 that there's a locking issue. The reference to the mail thread I
 started is here:

 (note that it's an issue with 8.1-* and 9-CURRENT).
 Thanks,
 -Garrett
