I think I have to switch to OpenBSD or 4.11 FreeBSD because this > box can't keep crashing. It refuses to do a crash dump. OK, when it crashes next and is sat at the "db>" prompt, type "tr" and press enter to get a trace. Copy this down (or have a serial console to capture the output). Also, try typing "call doadump()" and see if that succeeds in generating a crash dump. How were you trying to generate one before? Gavin
