Pull mirroring process is stuck for some projects
Problem
The pull mirroring process stopped working for https://gitlab.com/gitlab-community/gitlab.
The mirroring process starts, but it never ends
The last successful attempt was on 2023-05-29
I see a number jobs with started state that doesn't go to 0.
Investigation
I suspected a ListLFSPointers command as a reason for this problem first. Kibana link
But successful attempts from the past also have ListLFSPointers with cancelled status.
The job RepositoryUpdateMirrorWorker gets stuck. It's removed after 24 hours by StuckImportJob task. Kibana link.
In last 7 days, I estimate 1240 jobs that got stuck.
