Potential Issue with PHP-FPM 8.3.16: "WARNING: scoreboard: writer detected a potential crashed reader, decrementing reader count."

Description

Description:
After upgrading to PHP-FPM 8.3.16, we have encountered an issue that appears to occur only on certain services. Despite our efforts to adjust configurations and increase resources, the problem persists. We have not been able to identify any specific pattern or correlation during the PHP process that could be causing this issue. It seems to happen randomly. Although the number of errors is not large, they do appear consistently.

Error Message:

WARNING: scoreboard: writer detected a potential crashed reader, decrementing reader count.

Environment:

PHP Version: 8.3.16
Operating System (Docker image): php:8.3.16-fpm-alpine
Server Type:

pm = dynamic
pm.max_children = 50

max_execution_time=90
post_max_size=20M
upload_max_filesize=20M

Additional Information:
We have tried the following without success:

Any insights or suggestions on how to resolve this issue would be greatly appreciated. Thank you!
