[Bug]: Error in SolaceIO during autoscaling events ("Tried to start a closed message consumer")
What happened?
We observe this error frequently during peak hours in a streaming job when Dataflow decides to autoscale workers. It looks like a race condition inside SolaceIO regarding management of Solace JCSMP resources - see stack trace below:

Paweł, would you be able to share some logs from the worker that had this exception? especially if there are logs like:
SolaceIO.Read: Closing session for the reader with uuid
