What is WSAEADDRINUSE Error in Predator DNC

Problem

When opening a command with a Server Terminator, the error log shows "Socket(OpenPassive): Retrying WSAEADDRINUSE error" and "Socket(OpenPassive): bind socket error 10048".

Reason

Predator DNC is unable to open the TCP socket.

Solution

  1. Check for conflicts with other Predator DNC machines
    1. The best way to identify the problem machine is to cancel all machines, start up only the problem machine (confirm it starts correctly), then start up the rest of the machines. Now look for another machine showing the WSAEADDRINUSE error. 
  2. If you run the above test and it still fails, the TCP socket maybe be in use by another application on this computer. Identify this application and either change the TCP socket in that application or the TCP socket in Predator DNC.

  3. If another machine in Predator DNC is not using the TCP socket nor is another application, Windows may fail to release the TCP socket. The only known solution for this is to reboot the computer.
