Description:

This error occurs when the agent is unable to communicate with the internal TCP port used for inter-service communication. By default, the system uses port 5557. If this port is unavailable or already in use by another process or service, this error will be reported.

Resolution:

1. Verify port availability

• Check whether TCP port 5557 is free and not being used by another process or service on the system.

2. Change the port (if required)

• If port 5557 is unavailable or already in use, update the message queue port to an unused port number in the configuration file:

Path:
C:\Program Files\Vembu\VembuIntegrationService\conf\SGConfiguration.conf
Modify the MessageQueuePort attribute under the BackupCache tag as shown below: 

 <ObjectStorage>

    <BackupCache Enabled="0" MessageQueuePort="5557" MemoryPoolCount="10" />

 </ObjectStorage>

3. Restart services

• After making the change, save the file and restart the Delegation Service for the updated configuration to take effect.
