dccm got a fatal error

While I was engaged in moving one of my greylist servers from one
host to another, dccm logged this message and disappeared:

	Jan 14 18:53:02 electra dccm[5100]: [ID 349477 mail.error] clnt_xmit: zero client-ID; fatal error

What might have caused that?  Could it have been caused by my edits
to the grey_flod file or my add and delete of greylist entries?
Everything seems fine after a restart.
