A little context.

I have 3 secondary Pulp3 servers, syncing against a primary Pulp3 server, I kick off a sync of ~130 repositories per secondary in one go.

I've done this 3 times, and I've hit this deadlock on three occasions and so far only on this dell dsu repository.

Let me know if there is any more information that I can provide.

I can reproduce this problem at-will on core/3.11 and rpm/3.10. However, I cannot reproduce it, at all, on pulpcore-latest.

It's possible the new tasking-system has changed the timing enough that we no longer fall into the window. But there have also been A LOT of changes between 3.11 and Now.

The script I'm using to recreate is here:

https://github.com/ggainey/pulp_startup/blob/main/8750_deadlocks/repro_3-11.sh

(Same but with --autopublish for latest: https://github.com/ggainey/pulp_startup/blob/main/8750_deadlocks/repro.sh )

I'm going to try to reproduce on exactly core/3.14, rpm/3.13; I also have a lock-ordering theory that will try out on 3.11-et-al. Will report back here with results.

Update from QE - problem can be recreated on 3.14, but only by turning on the Olde Taskinge Systemme . Investigation continues.

Revision 6af3519b | View on GitHub

Fix occasional deadlocks when doing multiple similar syncs concurrently.
