CRRDG1119E Debug Secure Daemon failed to start because port port_number is invalid or is in use.
The Debug Secure Daemon runs in the background and listens for incoming debug connections. If another instance of the product is already running on this machine then the port is likely already in use. You can change the port in the workbench preferences.

Explanation

The Debug Daemon was unable to start on the secured port specified in the preferences because the port was invalid or the port was in use by another instance of the product.

System action

The Debug Secure Daemon does not start, and incoming sessions are not allowed.

User response

Ensure that the port is valid and no other applications are listening on the specified port. Alternately, select a different port for the daemon. Check the workspace log for any related messages.
