Need a never ending worker

[tarinisunil]

I have an Server which randomly produces job like a publisher. Monq is being used as a job queue. Consumer can consume whenever it is up. The issue is after one deque the worker stops processing jobs.
I have two queues main and retry, once dequed from main it will go in retry and will remain there always. It should be FIFO. I have created a worker with two listeners but it stops after processing one message. What am i doing wrong?
