I have a problem on my redundant server as it is always stopping and starting and after some time passes it is fully stopped. I cant seem to find what causes the problem. ```auto MasterTCPChannel 18Sep2019 17:57:31 (id=60) Shutting down channel.

Hi @emovspunk1996, @paul-griffith I have exactly the same symptoms on my 7.9.13 architecture. Have you solved your problem since? And How? Regards, ---
