I haven't tested the specific boundaries yet, but I will do that shortly. I *was* able to get a crash dump on the i386 system - Will post the details shortly. My amd64 system is a test system with ZFS, so I couldn't get a crash dump. Trying to work around that. On both systems, I used a 72K file (73,688 bytes) to test. Both systems would "lock up", and then a few seconds later kdb would come up. It wasn't an immediate thing, at least not on the i386 system. I wasn't able to watch the amd64 system since it's too far away to time.
