SYMPTOMS:

When Surrogate Socket starts, it logs "Inbound socket n error=24048, Specified address is already in use" followed by "Inbound socket n error=24038, Invalid socket descriptor passed to function."

MORE INFORMATION:

This problem occurs when another service or program running on the same computer is already using the specified port and IP address combination.

RESOLUTION:

Only one program or service may listen on a given IP address and port combination. Either remove the mapping or stop the other service.
