Since  version 8.3, an EMS server will report "Remote end closed the connection" or "Socket error, reason = ****" in the EMS server log (CONNECT trace option is enabled) when a client (usually a non EMS client)  tries to create a connection with an EMS server and immediately closes the connection. As an example, run the following command on a Linux machine to connect to an EMS TCP listener port. The "-z" option for the nc command scans for the daemon's listening port without sending any data.

“nc -z <EMS server hostname> <tcp port>”

The EMS server log will show the following log entry when the "CONNECT" trace option is enabled:

Remote end closed the connection
or
"Socket error, reason = ****" 

EMS server reported "Remote end closed the connection" or "Socket error, reason = ****" message after upgrading to EMS 8.3.
