Could you try using truss to see if, once it starts spinning, it's making system calls, or just stuck entirely in userspace? Assuming it's purely a userspace problem (perhaps triggered by syntactically poor output from the kernel), the next thing to do is probably to instrument your ipfw binary with either printfs or debugging symbols and see where in its execution it is spinning. Could you include a list of your IPFW rules also, please? I wonder if the kernel or userland tool contains a bug that is causing it to misbehave for some specific ruleset.
