Environment

CA directory: All Platform

Cause

The "Syntax Error" is misleading, most likely there is another process on the server already listening on the specific port.

Resolution

1. Open file <installDir>/dxserver//config/knowledge/ExampleSessionStore.dxc, obtain the value of snmp-port=port.

2. Use "netstat -nltup | grep port" command, verified that there is another process already running on the same port.

3. Stop or kill that process, then start Session Store again.
