I am occasionally getting tis error directly after running a transaction that failed. I have verified that the rollback occured both by walking through the code and looking at the table afterward.

The only way I have found to fix this is to stop my services and restart them. Is there a more graceful way to do this? It seems to only happen when I'm using a Transaction Key. I considered creating a random transaction key but am concerned about not releasing resources.

Thanks!
