hfaxd filling my logs with `-> Got a: 127.0.0.1[13] (how to stop this??)

All,

  I have a bizarre issue with hfaxd. When it is started, every 20 seconds, the
process kills itself and restarts and fills the log with 4-lines of text about
"`-> Got a: 127.0.0.1[13]".

(which prompts the question "Well, just what the hell did it get?")

  Here is a typical server startup (systemctl start hfaxd):

...
(this goes on forever...)

  My /lib/fax/hfaxd.conf contains only the default 2 lines:

LogFacility:            daemon          # syslog facility (want this 1st))
ServerTracing:          0x001           # just server operation

  The funny thing is I have 2 hylafax servers at 2 different location, both
identically configured, both on Archlinux, both with USR Courier v.everything
modems, both on ttyS0, and on one machine, I get no such filling of the log.
In fact on the (good) machine, I never get any of those messages:

# sc status hfaxd

Oct 23 01:25:17 valkyrie systemd[1]: Started Hyla FAX client-server.

(that's 3 days since the last kernel update and not a single "`-> Got a:
127.0.0.1[13]" message)

  On the other machine (the bad one), I get those 4-lines every 20 seconds.
What could be causing hfaxd to think it is getting 'a'? (I know it isn't
getting 'a', but "`-> Got a: 127.0.0.1.." comes from somewhere) It just seems
horribly wasteful for something to be continually restarting hfaxd and filling
the logs with 17280+ lines of logs every day.

  What could be causing this?
