Resolution

Follow the below steps to clear the data on the server i.e.

1. Stop the PAM Server

2. Can safely delete below folders: "data, scripts, TMP,  temp" from \PAM\Server\c2o
Note: On starting the service, the above folders will be created again based on workflow execution the content will be generated

3. Once service is up and running on PAM server, restart the Agent service (If any).
