Few Jobs becoming orphaned

[diegotl]

Describe the bug

I'm using Queues with one remote Redis instance. Sometimes a few jobs to get orphaned, that means, they are stored but not listed in their queue list. Manually putting them into their corresponding list fixes, they get executed. In the logs, from the instance where jobs are dispatched, I get few errors like connection was closed unexpectedly that are always followed by command failed. I could not yet confirm this, but I suspect those failed attempts are causing orphan jobs.

To Reproduce

Not clear how to reproduce it, but one way to try would be: regularly dispatching jobs to a remote Redis instance and trying to cause some connection problems.

Expected behavior

Something to prevent or some periodic routine that fixes orphaned jobs, making sure they will be executed at some point.
