Kubernetes containers exited with error code 139

[kwhui-m10c]

What happened?

We've tried to deploy our APIP application based on the frankenPHP version 1.3.3 (with base image dunglas/frankenphp:1.3.3-builder-php8.2/dunglas/frankenphp:1.3.3-php8.2) in a AWS EKS cluster.

When the site is getting busy, the containers start to exit with code 139 very soon and we don't see any specific logs output.

However we still can't reproduce the same issue by load testing using tools like k6 in our testing environment.

Are you building with xcaddy? Which PHP extensions are you using? Are you using a PHP framework? Are you also seeing the same error when updating to frankenphp:1.3.6-php8.2 or if you disable opcache?

Are you building with xcaddy?

Yes, we need to include additional modules, basically we followed the description in https://frankenphp.dev/docs/docker/#how-to-install-more-caddy-modules

We are using API Platform 3.1.5 + Symfony 6.4

We didn’t try either
