>Description:
	Netbsd frequently panics with the same problem after 1-4 days
	or a reboot. This is a problem that plagues Netbsd, and prevents
	it from using it as a stable platform. 

>How-To-Repeat:
	Use Netbsd in a heavy environment that exercises sendmail, web,
	pine, and about 30 or so shell users. 
>Fix:
	Don't have one, but how I wish I had one.
