For a few months now, we have been seeing these dozens of these warnings in /logs on a daily basis: Unicorn worker received USR2 signal indicating it is about to timeout, dumping backtrace for main thread As we usually run on stable, I assumed they would eventually go away when we jumped into the next major version which we did this week. We are now on 3.4.1, but the errors continue. backtrace activesupport-7.2.2.1/lib/active_support/broadcast_logger.rb:130:in `block in warn' activesupport-7.2.2.1/lib/active_support/broadcast_logger.rb:231:in `block in dispatch' activesupport-7.2.2.1/lib/active_support/broadcast_logger.rb:231:in `each' activesupport-7.2.2.1/lib/active_support/broadcast_logger.rb:231:in `dispatch' activesupport-7.2.2.1/lib/active_support/broadcast_logger.rb:130:in `warn' /var/www/discourse/lib/signal_trap_logger.rb:40:in `public_send' /var/www/discourse/lib/signal_trap_logger.rb:40:in `block (2 levels) in ensure_logging_thread_running' :187:in `loop' /var/www/discourse/lib/signal_trap_logger.rb:37:in `block in ensure_logging_thread_running' info Unicorn worker received USR2 signal indicating it is about to timeout, dumping backtrace for main thread config/unicorn.conf.rb:203:in `backtrace' config/unicorn.conf.rb:203:in `block (2 levels) in reload' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/rack-mini-profiler-3.3.1/lib/patches/db/pg.rb:69:in `exec_params' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/rack-mini-profiler-3.3.1/lib/patches/db/pg.rb:69:in `exec_params' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/activerecord-7.2.2.1/lib/active_record/connection_adapters/postgresql_adapter.rb:894:in `block (2 levels) in exec_no_cache' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/activerecord-7.2.2.1/lib/active_record/connection_adapters/abstract_adapter.rb:1004:in `block in with_raw_connection' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/activesupport-7.2.2.1/lib/active_support/concurrency/null_lock.rb:9:in `synchronize' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/activerecord-7.2.2.1/lib/active_record/connection_adapters/abstract_adapter.rb:976:in `with_raw_connection' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/activerecord-7.2.2.1/lib/active_record/connection_adapters/postgresql_adapter.rb:893:in `block in exec_no_cache' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/activesupport-7.2.2.1/lib/active_support/notifications/instrumenter.rb:58:in `instrument' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/activerecord-7.2.2.1/lib/active_record/connection_adapters/abstract_adapter.rb:1119:in `log' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/activerecord-7.2.2.1/lib/active_record/connection_adapters/postgresql_adapter.rb:892:in `exec_no_cache' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/activerecord-7.2.2.1/lib/active_record/connection_adapters/postgresql_adapter.rb:872:in `execute_and_clear' /var/www/discourse/vendor/bundle/ruby/3.3.0/gems/activerecord-7.2.2.1/lib/active_record/connection_adapters/postgresql/database_statements.rb:66:in `internal_exec_query' /var/www/d...

And, as mentioned there, the logs do seem to get truncated sometimes. And what all this looks like in /logs: [Screenshot 2025-03-07 at 12.18.50] Any clues on what might be causing these? Can I prove any other info?

FWIW, we have also seen sporadic reports from users with similar errors when editing some posts (usually quite long, although not close to the limit), where making tiny changes to the text seem to overcome the error (anecdotally: adding another period, replacing a dash, etc). Haven’t been able to find reproducible steps yet as I usually hear about it only when someone found the “magic trick” to it.

I’ve just noticed these warnings as well. When they start, they may have several recurrences within an hour or so, then stop. Until next time. I’d swear we didn’t have them until a few days ago. [image]

Which version are you on, @icaria36 and @Indra? We are on stable, but I’m wondering if this is also happening in tests-passed.

We are on 3.5.0.beta3-dev (3f353a726b).

I think have found something likely related to this and that may provide some more clues to the source of the problem. This gets a bit long-winded, so please bear with me. I noticed today that I have a couple sidekiq jobs that fail and have been retrying for at least a week with the same error as in the /logs. [Screenshot 2025-04-03 at 17.09.13] On the console, if I retry to rebake that specific post, it takes a long time (near 30s) and eventually ends in error lib/pretty_text.rb:239:in `eval': terminated (MiniRacer::ScriptTerminatedError) from lib/pretty_text.rb:239:in `block in markdown' from lib/pretty_text.rb:691:in `block in protect' from lib/pretty_text.rb:691:in `synchronize' from lib/pretty_text.rb:691:in `protect' from lib/pretty_text.rb:176:in `markdown' from lib/pretty_text.rb:302:in `cook' from app/models/post_analyzer.rb:30:in `cook' from app/models/post.rb:357:in `cook' from app/models/post.rb:825:in `rebake!' from (discourse):1:in ` ' After some experimenting, it seems it is due to a particular upload reference that is being used multiple times (25+) in the same post: [Screenshot 2025-04-03 at 17.11.56] The time for the post to rebake is proportional to the number of times that image is referenced in it (1-2 seconds per each use). If it is mentioned enough times, it eventually hits the timeout error. However, if another uploaded image is mentioned as many or more times, the rebake is always instant. Saving the same image and uploading it again doesn’t reproduce the problem. So the issue seems to be with a particular upload reference. If all this is not odd enough, it gets stranger. Noticing that the re-uploaded image was including the file extension in the upload reference, I tried appending .gif to the problematic upload reference and… then the rebake works instantly as it should – even when the same problematic image is used dozens of times. In other words, I changed something like ![foobar|15x15](upload://w5ilVpOCq4ZcvEahAisyiR1pzhu) to ![foobar|15x15](upload://w5ilVpOCq4ZcvEahAisyiR1pzhu.gif) and, somehow, that made this weird timeout error to go away. Guess: some reprocessing needs to be done to this image [e0ded3304aff1477bae442c0ead0050210dce4f0] and for some reason it repeatedly fails, extending the baking process long enough for it to eventually fail? I’m not sure how to go from here. In any case, this seems like a bug that could use some attention – maybe the @moderators can relocate this to #bug if they agree?

Seeing this same error on our instance when posting/editing/approving a topic with very specific Markdown content. It will load for a while and then throw internal server error.
