worker is not restarting when using xdebug on symfony project about frankenphp HOT 6 OPEN

I'm able to reproduce on a project I'm working on. Disabling xdebug seems to solve it. I'll step through with gdb later and see what causes it—like yours, it seems to be an issue with ending the request.

If you just exit at a random place in the script, does it still not work?

from frankenphp.

When I put exit into the public/index.php from the start worker is restarting continuously.
I let the first worker start and then put exit at the start of index.php.
Then I make the first request, this request works because it is already in memory.
Then second request goes into infinite loading, no new logs in container logs, seems like index.php is not run at all.

Weirdly setting xdebug.start_with_request=yes fixes the issue.

Interesting. If you turn on xdebug logs, does it give any useful information? I wonder if this might be an xdebug bug?

For the first request I see following logs

[281472447540704] Log opened at 2024-08-15 07:40:47.634757
[281472447540704] [Config] INFO: Control socket set up succesfully: '@xdebug-ctrl.281472447540704'

[281472447540704] [Config] INFO: Trigger value for 'XDEBUG_SESSION' not found, so not activating

But no zdebug logs for the second request

I tried now without a worker mode, it is working properly when worker mode is disabled.
