Answer
GMS requested a socket from the operating system in order to start sending a message to a remote location. However, the operating system responded that there are no sockets available.
In this case session Undefined requested a socket and the operating system gave an error code of Undefined.
This error suggests that there is an un-recoverable problem with the operating system (e.g. the TCP stack has become corrupt, the operating system has run out of resources, etc.). Gordano Support have seen this error occur when there is too little memory or disk on a Windows machine running GMS. When customers shutdown and restarted the system, the problem was resolved. You will need to investigate the system operating guide to discover why this error has occurred.
