Not sure if this is the right place for this post. But recently I have to do a zmcontrol stop/start to get the mail server to respond. When I do a zmcontrol status everything looks fine. In the logs. I see a line

Caused by: SSL peer shut down incorrectly.

It is in the log file quite a bit but I don't know if this is the cause of the issue. I can post the log file if you want let me know. Thanks
