-------------------------------------

Great to hear Yonik, sorry I couldn't have given you a working example of the issue, but glad you were able to duplicate it.  Please let me know if there is anything else I can provide.

> I have been unable to reproduce this in a test but this has come up at least 3 times in our environments.
