>Description:

	During the preceding 3-4 weeks the machine has panic'ed according
	to the traceback below 3 or 4 times. A dump is available and can
	be forwarded to netbsd.org if needed.

	The machine's main task is to probe a bunch (about 800) of routers 
	periodically and save usage statistics. Consequently the machine has a fair
	amount of network and disk activity, but not to any excessive degree.
