[Opensim-users] Questions about orphaned prims

[Chris]

I have a couple of regions that have logging on start up that say 
"Database contained an orphan child prim ... This prim will not be 
loaded.".  One of the regions is completely empty and still contains 
this logging.

A few questions about them:

What are orphaned objects/prims and how do they occur?

How can I recover them or at least fix the logging?

Does the presence of an orphaned object/prim indicate the original 
object has been lost or perhaps corrupted (For example, from the object 
owner's inventory)?

Logging Example:

17:53:35 - [REGION DB]: Database contains an orphan child prim Object 
5d72003b-5741-4d0c-87ca-d11a5e936696 in region 
91b75ca8-fdef-452d-998b-e1e50cf688b0 pointing to missing parent 
0ccb9f11-c83b-43b8-a01b-b75d2bd299e2.  This prim will not be loaded.
