Answer
A message has been sent to GMS and GMS Anti-Virus attempted to run a content or virus check on it. GMS Anti-Virus was unable to perform the check and produced an error.
In this case, session Undefined was processing a message from the server/client at Undefined apparently from Undefined for Undefined. When the check was attempted, an error code of Undefined was returned.
In order to resolve why this happened, you will need to check what the error code Undefined means in the KB entry about GMS error codes.
