I used both the Oct 15 and Oct 16 snaps to upgrade this vm and am seeing
repeated messages like the subject. With current sources I added the "abort"
tag to all pledge calls in the usr.sbin/smtpd hierarchy and built w/ debug
symbols. I've appended some dmesg complaints as well as the full dmesg.
gdb transcript:
