Hi,
Sometimes FMLE is taking a very long time to actually push the data into the server. You can restart FMLE and see if the problem goes away. Also, you can adjust the streamsExpireTimer inside the EMS configuration file to a bigger value (is in seconds), although we do not recommend that. When this happens, it is usually because FMLE has some troubles starting the encoding process in a timely fashion
Best regards,
Andrei
