Unit Version: 1.28.0
PHP Version: 8.1.13
When dumping (var_dump()) a very big variable in PHP (endless loop, circular reference), the application crashes with the following logs:

After that we get a 502 Bad Gateway from Unit. Calling the Control API (GET http://localhost/config/) will return an empty configuration, so the configuration is not reapplied. In the state folder at /usr/state/conf.json is still the correct configuration. If I apply this file manually with PUT http://localhost/config/ the reconfiguration is done successfully and the application works again.
