Seems the second error is freeze the app and drop the connection and load again only a few mins later. This happened last time when I try to change my dark color scheme and saving it in user interface page the save button stucked into Saving… position and not turned to success. After this the site not loading for a few minutes but this seems to me pretty random.

Thanks :slightly_smiling_face:

Interesting one @tgxworld, are we seeing any of these as well?

We are seeing Unicorn timeouts but they are happening for a wide variety of reasons.

I did just realise that logster truncates the message so we can’t view the full backtrace easily. I might need to improve this logging so that we only include backtraces of the Discourse app.

Update: I didn’t see these errors since then. :slight_smile:
