GWHA question

I've configured GWHA for the first time on my SLES 12 SP3/GW 18.1 system. Seems to be working fine. In my logs (/var/log/messages) I see the following lines:

<hostname> xinetd[56070]: FAIL: gwha service_limit from=<ip_address of host>

Everything seems to be working fine. What would this message be referring to?
