I found that it is throwing this error:
```plaintext

if read.wait_readable([0, @next_check - Time.now].max)

then Puma restarts itself. What should I do to prevent this?
Edited: This seems to be [a problem belonging to Puma](https://github.com/puma/puma/issues/3620) since Ruby 3.4.0. Solved by disabling YJIT.
