Make sure your spamass-milter has debugging symbols (installing
binaries usually strips them, so build the port and manually copy the
executable to its final location), and run:

$ gdb spamass-milter spamass-milter.core
(gdb) info threads
(gdb) thread apply all bt

If you run the milter as a non-root user it may not be able to create
its corefile; you can force cores to a publicly-writable directory by
running "sysctl kern.corefile=/usr/tmp/%N.%P.core" as root.

Milters shouldn't affect each other.
