Hi Team,

Gitlab 18.1.3 Self Managed

We recently faced this issue on one of our instances where we noticed -

• Jobs stuck in pending state waiting to be picked up by the Runners.
• Merge Requests stuck at Your Merge request is almost ready!

In the Sidekiq Dashboard it showed us that Sidekiq used all the threads and was at 100% use. For some reason the queue still had ProcessCommitWorker, UpdateMergeRequestsWorker, ProcessScheduledMergeWorkerMerge from a month ago still stuck although the Merge Requests were successful.

Restarting sidekiq has helped clearing out the queue.

I looked at an already existing issue which suggests something similar - #554613 (closed).

Another issue related to sidekiq fixed in 18.1.2, is there a patch coming to fix this in 18.1?

Thanks in Advance
