Edit report at https://bugs.php.net/bug.php?id=81444&edit=1 ID: 81444 Comment by: Wanda6123Mares at outlook dot com Reported by: drissi dot reda4 at gmail dot com Summary: php-fpm crashes with bus error under kubernetes Status: Assigned Type: Bug Package: FPM related Operating System: debian 11 PHP Version: 8.0.10 Assigned To: bukka Block user comment: N Private report: N New Comment: The bug report suggests that it is related to the use of transparent huge pages (THP) in the kernel. A possible workaround is to disable THP on the host machine by running: echo never > /sys/kernel/mm/transparent_hugepage/enabled Alternatively, you can try to use a different PHP container image that does not use bullseye as the base OS, such as php:8.0.10-fpm-buster or php:8.0.10-fpm-alpine.

The php-fpm process crashes with "Bus Error" at boot. However I can fix this, by disabling hugepages from sysctl.conf. I need a way to use php-fpm under my kubernetes cluster without disabling hugepages. kubernetes version: 1.21 containerd version: 1.4.9 OS: debian bullseye kernel: 5.10.0-8-amd64 Test script: --------------- Deploy any php-fpm container in any kubernetes cluster with hugepages enabled. Expected result: ---------------- not a crash of php-fpm Actual result: -------------- a crash of php-fpm ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81444&edit=1
