Checking geometry results in "shape(s) could not be checked"

[JMMFIRE]

I'm  working to diagnose an issue with registering a table with my geodatabase. I believe it is related to an issue I've observed with some feature's geometries. 

When running the Check Geometry tool I get the resulting message: 

     FINISHED: 55202 total feature(s) fetched.
               55199 shape(s) passed geometry check.
               3 shape(s) could not be checked.
               0 shape(s) have a geometry error.

No records were added to the output table either. How am I to determine which features' shapes were not able to be checked and why?

What you could do is make a copy of the table in question so as to preserve the original table.  Then run the Repair Geometry (Data Management) GP tool.  Per the documenation, it states "Inspects features for geometry problems and repairs them. If a problem is found, a repair will be performed, and a one-line description will identify the feature, as well as the geometry problem that was repaired."

@JMMFIRE Did you ever find a solution? I'm running into the same issue of having '4 shape(s) could not be checked'. I made a copy of the layer and ran a repair, it found one feature with null geometry. But when I deleted that feature, it still had 4 shapes thar could not be checked so I don't think that addressed the issue.

@ChelseaLynn - when you run the Repair Geometry tool, are you using the layer from the Contents Pane?  If so, try running the tool again but use the feature class from the Catalog Pane or the Browse button for the Input Features parameter instead.  Is the result still the same?
