System: FreeBSD yoga 4.9-STABLE FreeBSD 4.9-STABLE #1: Mon Nov 24 00:17:34 EST 2003 root at yoga:/usr/obj/src/sys/YOGA i386


>Description:
system had been running fine with a kernel/world 
last cvsup'd and built Sept. 18th. 
cvsup'd last week all builds since have been unSTABLE. 
any task that has a significant memory and disk load 
can cause the system to crash.
added kernel debugging to kernel.
dmesg followed by 3 example crashes below.
