Hello i2b2 team,

I have noticed a bug with the 1.7.12a version of i2b2. Namely, a query will be cancelled when a query moves from the SMALL_QUEUE to the MEDIUM_QUEUE. An error message is generated but only if the Wildfly logging level is set to DEBUG. This is the error message:

2021-06-24 11:02:04,323 FINE [com.microsoft.sqlserver.jdbc.internals.TDS.Writer] (Thread-120) TDSWriter@2b18e9b1 (ConnectionID:3): sending attention...
2021-06-24 11:02:04,342 FINE [com.microsoft.sqlserver.jdbc.internals.SQLServerException] (Thread-109) *** SQLException: com.microsoft.sqlserver.jdbc.SQLServerException: The query was canceled. The query was canceled.

Any assistance would be greatly appreciated.
