PHP-FPM worker just crashes with no error messages

[tasso85]

I am trying to develop an application using Laravel+InertiaJS, and I noticed that I have a problem where sometimes a PHP-FPM worker would just crash without having any error message to check; specifically, I am using Apache 2.4.52 with PHP 8.3.8.

In the FPM log I just see

[21-Jun-2024 10:43:51] WARNING: [pool www] child 8414 exited on signal 11 (SIGSEGV) after 543.963041 seconds from start

and the web UI shows a modal (I think that is generated by InertiaJS itself) with the message

Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Apache/2.4.52 (Ubuntu) Server at localhost Port 80

in this specific case, I step-debugged my code up to the line where I try to create a new entity:

$quote = Quote::create($quote + ["contact_id" => $contact->id]);

Here, $quote is an array where I initially stored the needed data, in order to later create the model; on that line, it just dies without generating an exception or anything I can check to understand what went wrong.

How do you perform debugging in this cases?

I noticed that if instead I run the app via php artisan serve it generates a proper exception; however, I'd like it to work with Apache too, as that is what might be used in production.

Just for curiosity, I tried the Nginx+PHP-FPM combination, the result is the same, only slightly different message in the modal

502 Bad Gateway
nginx/1.18.0 (Ubuntu)

So it would seem that the culprit is PHP-FPM itself; however, I wouldn't know how to have it dump a proper log...

Anyway, it seems to me that this is going quite OT for Laravel, unless someone else here has encountered similar problems in the past; if not, maybe I should just close/delete this thread?

Hi. Could it be related with the fact that php artisan queue:work without ---once is a long term php process and that some setup from your php fpm shuts it down after a while?

I was not talking about the event queue though, but just serving the app.

I have the same problem, do you have any solution?
