How do I clear stuck/stale Resque workers?

Question

As you can see from the attached image, I\'ve got a couple of workers that seem to be stuck. Those processes shouldn\'t take longer than a couple of seconds.

Answer 1

I've cleared them out from redis-cli directly. Luckily redistogo.com allows access from environments outside heroku. Get dead worker ID from the list. Mine was

55ba6f3b-9287-4f81-987a-4e8ae7f51210:2

Run this command in redis directly.

del "resque:worker:55ba6f3b-9287-4f81-987a-4e8ae7f51210:2:*"

You can monitor redis db to see what it's doing behind the scenes.

redis xxx.redistogo.com> MONITOR
OK
1380274567.540613 "MONITOR"
1380274568.345198 "incrby" "resque:stat:processed" "1"
1380274568.346898 "incrby" "resque:stat:processed:c65c8e2b-555a-4a57-aaa6-477b27d6452d:2:*" "1"
1380274568.346920 "del" "resque:worker:c65c8e2b-555a-4a57-aaa6-477b27d6452d:2:*"
1380274568.348803 "smembers" "resque:queues"

Second last line deletes the worker.
