Hi Don
From the beginning 2016/7/6 28 user have this problem. I reset device(Tell Traveler Reset * <user name>) and device sync but after a while has same problem. "Traveler: WARNING <user name> Client has sent 11 effectively empty messages and the server has nothing pending, so this sync will be stopped to avoid infinite sync loops"
I dump user file
