8753.0. "malloc_check_checksum: memory pool corruption (kmem_debug=1)" by BIS10::BRUSCHE () Fri Feb 07 1997 09:09

	Below panic stack trace is from a system that had kmem_debug=1

	I submitted the crash_data to CANASTA (Case=735510064Q1BRO), but
	apparently it does not know of any similar cases.

	Anyone recognizing this footprint ?
