I seem to get this error randomly (about weekly). I am running FMS 16.0.2 WebDirect (only) on a high-end server. If users are logged in, it shuts them down. It appears to happen at random times whether users are on the system or not. I have created a Windows script that restarts the WPE every minute if it has shut down, so it fixes itself. However, it is annoying if users are logged in. Any suggestions?
