How to get a handle on open Redis connections

[slippyex]

Hi all. I am currently in the process of migrating BullJS to BullMQ and finished everything so far. Processing looks like it's done before. The only thing I'm wondering about is the amount of open Redis connections. They seem to ramp up and stay (orphaned) once a job finished. In our scenario, majority of the workers are sandboxed and we have a handful of scheduled jobs.
Now to the key question: Is there a recommended way to handle finished workers? In the bundled tests I see, that all instances (Queue, QueueEvent and Worker) have a function "close(force: boolean)" ... Should we close them, once a worker finished?

Any recommendation is appreciated. Thanks in advance.
