Workers stall and do nothing

[akashkumar58-zz]

I am able to see increasing queue length using qmonitor. But after receiving a bulk of tasks all workers stall. CPU utilization is almost 0 during that time period. All queued tasks execute after the timeout period which I have specified in my settings.py file. During that timeout period workers remain idle. I am not able to understand why workers aren't doing anything even if they have pending tasks on queue.

There was a problem in my design of tasks.
