I was in the middle of reading a message in mutt (my MUA) on the console and the system just froze. I was also cvsup'ing ports on another vty at the time. There was no way to get a dump or backtrace. Nothing, including networking, was responding. Here are a few things you might want to try: 1. Check your syslog to get an estimate of when the machine dies. Is it during high disk activity? Mine did it during a ports cvsup. Could it be doing it in relation to the /etc/security stuff? Does it happen around the same times every day? 2. Build a kernel with GDB_REMOTE_CHAT and try a remote gdb session against the kernel? Not sure how much information this will provide, since the machine will most likely stop responding to the remote gdb. 3. Figure out when the problem started happening for the first time and see what was commit'd around then. Incidentally, I've also noticed that my machine freezes on reboots. When I panic or when I issue a system reboot, my kernel never actually manages to reboot the system. It hardlocks after showing the system uptime. I've even tried turning ACPI off in the BIOS and it still does it.
