Issue
Getting LON messages TException E_QUEUE_FULL {LonAsyncRequest} in the standard output window.
Environment
R2, Niagara, Lon Service
Cause
If also in the message there is a line that includes: "lonextras.control.PollSnvtTempSetptCmd.execute" these messages are being caused by the use of the special object from the LonExtras jar called PollSnvtTempSetptCmd.
Resolution
When the station is booting up the PollSnvtTempSetptCmd object will begin its polling function before the station has finished rebooting causing the queue to fill up before the station starts. There is an object in the LonWorks jar - Conversion container called SnvtTempSetptCmd that will perform the same function as the PollSnvtTempSetptCmd except it does not poll which is not necessary in most cases. Replace all PollSnvtTempSetptCmd objects in the station with the SnvtTempSetptCmd object.
