GMS failed to deliver a message to a remote server and is going to return the message to the sender.
In this case, session Undefined was was processing a message to be delivered to the server Undefined (IP address Undefined). The local folder name is Undefined and the message is from Undefined to Undefined. The message is Undefined bytes in size and has been waiting for delivery in the outbound GMS queue for #p8#.#p9# seconds.
