Description of problem:

(cloned from https://pulp.plan.io/issues/2835)

Summary
=======

Restarting a worker that is currently executing a task will leave that workers in a broken state. This issue can reproduced on both Celery 3.1.x and Celery 4.x, but only while using Qpid as a broker. I was not able to reproduce this issue while using RabbitMQ as a broker, using either version of Celery. I was also not able to reproduce this issue on versions of Pulp prior to 2.13. The means of shutting down the workers also does not appear to matter, e.g. "systemctl restart" and "pkill -9 celery; prestart" both work the same.

Repro
=====
1. Start pulp
2. Begin a task (e.g. sync)
3. While the task is running, restart the pulp worker running the task
4. After the worker has restarted, begin another task
5. Observe that the tasks are perpetually stuck in waiting


Version-Release number of selected component (if applicable): 6.3 beta, pulp-server-2.13.4.4
