Databricks Connect - driver error

[Bagger]

Hi 

We are experiencing instability when executing queries using Databricks Connect.

Sometimes we are unable to receive the full result set without encountering an error with the message "Driver is up but is not responsive..."

When we run the same query directly through the Databricks UI, the problem does not persist. 

Does anyone have an idea to what the problem is and what a potential solution might be?

@Retired_mod thank you for your answer.. Our issue is that we can actually connect to the cluster and receive data, but sporadically the error occurs. The potential causes (and solutions) you list does fit our issue.
