Requests with large body is causing freeze/crash

[tomme87]

What happened?

When I make POST request with a body larger than ~15KB the request freeze forever.
There nothing in the logs and the request do not reach the application at all.
If I cancel the request and run it again the container is killed with error code 139. still nothing in the container log, but I get a segfault running dmesg on the host.

The issue only happens with frankenphp 1.4.4. 1.4.3 do not have this issue.

Caddyfile:

{
    {$CADDY_GLOBAL_OPTIONS}

    frankenphp {
        {$FRANKENPHP_CONFIG}
    }

    log {
        format json
    }
}

Is this happening only with xdebug enabled?

[tomme87]

Is this happening only with xdebug enabled?

No, it also happens with xdebug off.

[AlliBalliBaba]

Hmm I'm not seeing any other special extensions. Are you posting a form-data or multi-part-encoded body? Or just 15KB of raw data.
Are you using any framework? Is it failing for every endpoint or can you share some reproduction code on a specific endpoint that the segfault happens?

Not much actually changed going from 1.4.3 to 1.4.4, could also be related to a general PHP update.
Might also be worth trying if the same thing happens on FrankenPHP 1.5.0.

[tomme87]

I'm posting raw data (binary data, like a png)

I'm using Symfony 7.2. It's failing for every endpoint. Even for routes I have not configured. index.php is never reached.

The issue still happens with FrankenPHP 1.5.0.
I see that with FrankenPHP 1.4.3 I'm running PHP 8.4.4, but with FrankenPHP 1.4.4 I'm running PHP 8.4.5, so it might be a PHP issue.

If I get time I can create some code to reproduce the issue.
