Some main points are- The Target Table where insert is going is empty table- Select statement as itself is working geting 10K records in few sec- Tried to create new table to insert but still not worked- Insert session is showing very high wait on CPU and taking big CPU time- Bouncing database and running insert worked first few min but as App is started , it is again hanged and never complete
