Today we noticed that it’s incredibly slow, if possible at all, to upload new avatar photos. It’s also been incredibly slow to load some (but not all) users’ larger avatars on the pop-up user cards or the full-page profile. Updated to 2.5.0.beta2 (ae3220fb88) hoping that would help but no luck.
In https://discourse.example.org/logs we see the following type of warning when trying to upload a new avatar image file through the user profile page:
DistributedMutex(“upload_2_TEST.jpg”): held for too long, expected max: 60 secs, took an extra 2 secs

There are also some other items in /logs that seem to be related:
- [Warning] DistributedMutex(“optimized_image_23_120_120”): held for too long, expected max: 60 secs, took an extra 5 secs
- [Error] ‘hijack uploads create’ is still running after 90 seconds on db default, this process may need to be restarted!
Here’s what the UI looks like when attempting to upload an avatar image, after eventually timing out:
