Could this be that whatever is supplying the common disk used to keep heartbeat failed? That way, both nodes would be unable to keep updating the shared disk and the usual response is to terminate all services to avoid getting in the way, i.e. to panic/abort. We've had a Oracle RAC database cluster do this before. not pretty, but it is the best course of action to avoid damage.

CRASH(8) BSD System Manager's Manual CRASH(8)
NAME
crash -- examine and debug system images
SYNOPSIS
crash [-M core] [-N kernel]
DESCRIPTION
The crash command is used to examine and debug system images.
If run without any arguments, crash operates on the running system.
The options are as follows:
-M core Operate on the specified crash dump instead of the default /dev/mem. Crash dumps should be from the same version of the system
and same machine architecture as the running version of crash, and must be uncompressed.
-N kernel Extract the name list from the specified kernel instead of the default /dev/ksyms.
The command syntax used by crash is the same as the in-kernel debugger. See the ddb(4) manual page for more information.
Operations and facilities that require a running system, such as breakpoints, are not supported by crash.
crash does not provide pagination. However, by using the pipe symbol, output may be sent to commands available from the shell. For example:
crash> ps | more
crash> ps | grep ioflush
SEE ALSO
ps(1), vmstat(1), ddb(4), pstat(8)
HISTORY
The crash command appeared in NetBSD 6.0.
