Issue while starting the K2 Blaclpearl service, its moving to "Starting" status instead of "Running" status. Even though the service is showing as “Starting” all the functionalities are working as expected.  To see exact problem when K2 service started in console mode. To troubleshoot further, stopped the K2 service and ran the service in console mode to trace the error
