Set ddb.onpanic?=1 in sysctl.conf. The kernel will fall into its
debugger (ddb(4)) upon crash, print a backtrace with some useful
info and then wait.

uh,,,, when it's remote, it's better to save kernel and corefile from
safecore, and analyze that (ddb.onpanic=0)

Huh, typed too fast... sorry.

If savecore(8) manages to get a core file out of swap, use crash(8). The description section of savecore(8) gives useful pointers, especially the -M/-N parameters (see dmesg(8)).
