Invalid value for Index Name

I continue to get this error when adding an Index for some geodatabase tables within a python script:
[INDENT]ExecuteError: Failed to execute. Parameters are not valid.
ERROR 000192: Invalid value for Index Name
Failed to execute (AddIndex).
[/INDENT]The names for the indexes seem to match all the requirements (16 characters or less, not starting with a number and no spaces). So what am I missing??
This error happens inconsistently. Meaning, it will create the index for one of the table views and move on to bomb at the next add index. Then I "fix" that index name, rerun and it will bomb at the previous index. However, the script is running these processes on table views, so it should not be an overwrite issue.

Attached is a sample of the line of code that is bombing.
