	You will, perhaps, see 'core' files at your $POSTOFFICE/transport/
	(If not, you need to restart the scheduler with environment
	 "ulimit -c unlimited" setting.)

	It sounds like something I have seen recently too, but at
	different transport agent (smtp, in fact).
	I do think that that got cured at 2.99.55.

	But no, I can't remember what was the reason, nor I see it logged
	anywhere obvious.

	Getting a post-mortem backtrace from the core-file would help.

	# file $POSTOFFICE/transport/core
	(core of 'mailbox' ?)
	# gdb $MAILBIN/ta/mailbox $POSTOFFICE/transport/core
	(gdb) where
	... (the interesting report is here) ...

	All that assuming you have installed the binaries with debug symbols
	in them..  Helps doing backtracks, and doesn't need all that much of
	diskspace anyway.
