How to test maxStalledCount?

[selient]

My bull repeatable job queue has stopped working twice in last two month,
and I checked the document found this "maxStalledCount" I can set.
But how do we manually test how this works?
Is there any method can stall a job?

Can you be more specific regarding "stop working" ?

@selient just restart a worker while the job is in progress, then after some time (determined by lockDuration) you'll notice there're new hash field appeared on a job key, called stalledCounter. Job would be restarted only while this value less than maxStalledCount.
