Stream not found STATE_ID=41260

I am trying to add a feature into Oracle Enterprise Gdb, getting a "Stream not found" error??

The layer is available in SQL Developer, SDE cannot see it??

I tried to Register it, in case it was not present in A/D tables. Still got "Stream not found" error??

Also states there is a Lock conflict??

Any pointers to resolve this would be appreciated.

The ArcGIS Service had crashed. I tried to restart the Service,there is still a Lock.

Do I need to stop ArcGIS Service in Windows Services then check the mxd again??
