Connection is Closed Error in Multi-threaded Mode of DQD

[katy-sadowski]

When I run DQD in multi-threaded mode, none of the checks run, I just get this error "Connection is closed" on every check. Another user reported the same: OHDSI/DataQualityDashboard#651

I'm not sure if this is DatabaseConnector, ParallelLogger, or something else.

I am on Snowflake and on the latest versions of DatabaseConnector and ParallelLogger.

Appreciate any help / insight!
