Resolution:
This error code indicates that GMD failed because the message was not acknowledged within time to meet the message's delivery timeout property. This error number is used only in GMD_FAILURE messages, not in the global SmartSockets error number accessible with TutErrNumGet. This error number is applicable for both TipcConn* GMD and TipcSrv* GMD. It is the publisher itself that creates this error message. All other GMD error codes are signaled by RTserver and sent to the publisher in a GMD_NACK message.

This is the only GMD error you will get when you use our peer-2-peer Conn API.
