I've seen a couple errors similar to the following occur in the last couple of weeks. We recently migrated from 1.0.9 to 1.5.4. I found the referenced PR adding the concurrency manager but wonder if it is possible the database got in a somewhat invalid state prior to this change? Is there something that I can validate in the database to ensure it is consistent or process to fix?
