Answer
GMS has told the remote system to try sending the message later because there is not enough disk space available locally. The remote system should try sending the message later when more disk space may be available.
In this case, session Undefined is replied to a connection from Undefined.
To resolve this issue you should create some additional space on the disk that contains Gordano software. If the remote server complies with Internet Standards, it should hold the message and attempt to resend it later (in the hope that disk space has appeared).
