Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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
