Hi Shafeeq,
Was the sum stopped in between or process got killed if yes to a clean stop/start of SUM and retry the Phase again.
The issue seems to be with defunct process of your SUM. And check the lock file in SDT directory after stopping the SUM and clean it up if required.
also do verify your sapstartsrv and sapcontrol process as it mentioned the connection to SAP instance 05 is broken too. SUM check sapstartsrv for the system status.
Let us know the details.
Regards,
Ram
