mt_shm_remove: WARNING: may not have removed all/correct segments.

When the operating system tried to remove the shared-memory segments associated with the database server, the last segment did not equal the last segment registered internally. This situation is probably due to the unexpected failure of the database server.

Action

Remove any segments that were not cleaned up.
