Error 7249 and 7209 in AppServer server log a few seconds later
Invalid state for : Current state = (7249)
Progress.Open4GL.Exceptions.SystemErrorException: Broker System failure:
Invalid state for deallocate: Current state = STATE_RECEIVING (7249) .

FACT(s) (Environment):
Progress 9.x
OpenEdge 10.x
All Supported Operating Systems
CAUSE:
Because AppServer client was running slow, user killed client process, therefore the broker could not deliver the message to the client and generate the errors
FIX:
Address slow application performance first to avoid user killing clients causing broker errors
