Are you seeing messages like:

	fhfss /netbsd: panic: malloc: out of space in kmem_map

or

	fhfss /netbsd: mb_map full

in the messages file or on the console?  The symptons of the panic was
what you'd call a "spontaneously reboot".  I had this problem when
building a ccd with 6x RZ28's, and solved it by added the following
lines to my kernel's config file:

	options 	"NKMEMCLUSTERS=3072"	# 4K pages in kernel malloc pool
	options 	"NMBCLUSTERS=6144"	# extra mbuf clusters
