That seems to comport with the theory I suggested before, that you were
sending an incorrect message length word --- although this additional
evidence indicates that the sent length is too short, not too long
which is what I'd been thinking. Or possibly you left out required
field(s) of the message. Anyway it's expecting a null-terminated string
and not finding one in the remaining message data.
