This is a repeat of some email I sent out on 23 Oct, this time going to
a slightly larger audience.  The same crash happened again.

If there is any additional information I could gather that could help to
find the bug, please let me know.

My NetBSD-1.3H/i386 (built from sources supped around Oct 16)
system crashed last night.  I've typed in the following messages
by hand, so there may be some errors:

uvm_fault(0xfdc21820, 0x0, 0, 3) -> 1
kernel: page fault trap, code=0
Stopped in ypserv at   _amap_copy+0x23b:   movl  %ebx,0(%eax,%edx,4)

What other information might be handy for the next time this happens,
and what would I type to get that information?
