Thanks Brian.

It looks like the worker timeout.

Jan 31 09:19:30 pulpp-ob-581 gunicorn[147883]: [2020-01-31 09:19:30 -0500] [147883] [CRITICAL] WORKER TIMEOUT (pid:147898)

How do I change the timeout setting in settings.py?

What do the logs say about why the gunicorn process serving pulp-api is dying? Would you want to file an issue https://pulp.plan.io/issues/new so we can do some testing?

As an aside, I recommend using paging when pulling so many items from an API. You could decompose your large request to more, smaller requests like:

http GET localhost/pulp/api/v3/content/rpm/packages/ offset=0 limit==10000 repository_version==/pulp/api/v3/repositories/rpm/rpm/2f46d319-7997-4e86-b159-8babee4aba19/versions/1/ --timeout=200
http GET localhost/pulp/api/v3/content/rpm/packages/ offset=10000 limit==10000 repository_version==/pulp/api/v3/repositories/rpm/rpm/2f46d319-7997-4e86-b159-8babee4aba19/versions/1/ --timeout=200

What's interesting about more, smaller requests is you can likely get the data out of Pulp a lot faster since you can engage more gunicorn processes in parallel. Conceptually one large query is attractive though, so maybe we could improve that if you file it.

Another idea is to limit which fields are being returned to get at the data you need faster.

All the best,

The rhel 7 servers rpm repo has more than 26k packages. I got an "502 Bad Gateway" error if I tried to list all of them

What could cause this? Is there a fix?
