You should be able to get the coredump if a process is crashing and have
JTAC take a look at it.  Also, I'd advise maybe enabling some IS-IS
traceoptions to monitor what's going on - when it crashes again there might
be something in the log which provides more information, like perhaps the
device received a Malformed IS-IS LSP or something along those lines...
