Symptoms

When Microsoft Lync Server 2013 or Skype for Business Server 2015 Response Group Service (RGS) crashes one or two times a week with the announcement service, the affected RGS restarts automatically. However, no agents can receive calls that come through this RGS. You may see the following events in the Event Viewer:

Cause

After the RGS crashes, it will try to restart automatically. Unfortunately, the Match Making service that's a component of the RGS doesn't connect to any Front-End server and therefore no agents can receive calls coming through RGS. The only way to make RGS in a functional operation is to manually restart the RGS on each Front-End server.
