Hi
Our Puma server periodically stops working, and returns to command line without error message.
Nothing has changed to the configuration, but today, for the first time, the attached message was raised.
I hope this is a good clue!

Best regards,
Fred

Based on the error message and control frame info, it appears puma is allocating an object during garbage collection, which would be a bug in puma. Try upgrading to puma 4.3.3 (the latest release), and if you still have the same issue, you probably want to contact the puma developers on GitHub: https://github.com/puma/puma/issues
