Instance has been shutdown however the shared memory segment is not removed.


RDBMS instance shutdown failed to clean-up all active bequeath connections.

The status column for the problem shared memory segment has a flag status of 'dest'.
The flag "dest" in the status column means that SHM_DEST flag has been set for that memory segment.
Setting this flag allows the operating system to automatically clean up the shared memory segment when it is no longer used.
