SearchIndexingError: There was an error indexing content ('Groups').

We are getting a SearchIndexingError where we were unable to track down the root cause.  It is occurring hundreds of times a day and we would like to see what is happening and correct the data/indexing issue. 

There is no extra exception information other than the stack trace.  Has anyone seen the below or have any ideas how to trouble shoot?

FYI:

Telligent version10.3.2.7882
