GMS attempted to send a message to a remote system but the remote server was not available to accept the message. Therefore GMS has re-queued the message and will try again later.
In this case, session Undefined was attempting to send a message to the domain Undefined. The message could not be delivered so GMS has queued it for retry at Undefined:Undefined:Undefined. The queue was set to retry because "Undefined".
This is the expected result, no action is required by you.
