For some time the FileMaker WebServer is switching off by itself. This is happing infrequently, weekly or so. I hoped this will change after upgrading to FileMaker 16. The used concurrent connections are about 6-8 of 20 in average. XML is enabled, PHP disabled. Database cache set to 2048 out of 16GB.
What could be the reason for the WebServer switching off by itself infrequently?
