The problem is that your TCP/IP connection with the server is being severed.

This can happen for any number of reasons, including:

  1. the server crashed
  2. the server was rebooted
  3. the server lost its network connection
  4. the client lost its network connection

You just need to handle these unexpected disconnects by attempting to reconnect and re-issuing the command.
