EMT trap on UNIXPC

[Todd Day]

I was doing a LOT of stuff simultaneously (downloading news, unbatching news,
multiple windows, a compile, etc) when all of a sudden my machine locked up.
It happened just as I wanted to spawn a new rn.

I had to reboot.  The only clue I have as to why this happened appears in my
/usr/spool/uucp/LOGFILE:

nessus!uucpadm (3/11-9:48:09) (C,28705,22) REQUESTED (S D.nessu24f1470 D.nessu24f1470 news)
nessus!news (3/11-9:50:37) (C,28705,23) 25 (INTREXIT)
nessus!news (3/11-9:50:37) (C,28705,23) intrEXIT (SIGNAL 7)

I also got a core dump in /usr/lib/uucp.

signal 7 is EMT instruction, according to signal(2).  What is this EMT?
Why did I get it?
