Dan: I too am having frequent SAM crashes -- maybe a couple or more a week.
I've resorted to using Daemontools to see that it keeps going, because even
a few minutes down lets the spams flood in.

I had a core dump but apparently deleted it.

No doubt, I'll have another soon. Dan, how can I convert the dump into
something for you to use of value. I've never had much success in
translating the dumps, but if you'll tell me the procedure, I send the next
one.

Running:
FBSD-4.10-R
Sendmail-8.12.11
Spamass-milter-0.2.0_3
p5-Mail-SpamAssassin-2.63_2
perl-5.6.1_15

BTW: Will the milter-greylist-1.2.2_1 co0exist with the above....??
I tried it yesterday on a test box, but the SAM kept crashing on it too.
