Hello SSP,

→ As per the log cuts, we could see connection issue between pgms22cma01 and nwccewprdma01 over CVD port 8400 and due to which it is not able to spawn the DDB engine.

Error returned r-1=Connection failed on pgms22cma01 with these errors: 1) No direct tunnel to nwccewprdma01; 2) Couldn't bring up any automatic tunnels to nwccewprdma01*nwccewprdma01*8400]. Check Network Connectivity.)}]

→ Make sure the connection between the required servers “pgms22cma01 and nwccewprdma01” is fine over the CV ports i.e 8400
