Cloud Run Uncaught signal: 11 after upgrade Laravel 9

Question

I upgraded my project to Laravel 9 with PHP8. But since I deployed on Cloud Run I randomly have this errors in the Cloud Run logs :

Uncaught signal: 11, pid=17, tid=17, fault_addr=4294967296017.

So the query is aborded with 503 error : GET 503 898 octets 682 msChrome 109 https://...

Here is my php-custom.ini :

max_execution_time = 500
upload_max_filesize = 40M
post_max_size = 40M
memory_limit = 800M
max_file_uploads = 100

And my opcache.ini :

[opcache]
opcache.enable=1
opcache.enable_cli=1
opcache.revalidate_freq=0
opcache.validate_timestamps=0
opcache.max_accelerated_files=32531
opcache.memory_consumption=256
opcache.max_wasted_percentage=10
opcache.interned_strings_buffer=64
opcache.fast_shutdown=1
opcache.jit_buffer_size=100M
opcache.jit=1235

And my dockerfile :

FROM php:8.2.3-apache as base

I don't know how to reproduce the bug because it's very random, but I noticed the error appears after the Cloud Run cold start. I don't know if the problem is caused by my opcache config. My Cloud run service has 1 CPU and 2 GO memory.

I don't know how to fix that.

Edit

I'm adding 2 graphs when I got the error :

Answer 1

I solved my problem. That is not about Cloud Run. The problem is the JIT configuration. I changed this:

opcache.jit=1235 

to

opcache.jit=1255

According to this : https://php.watch/versions/8.0/JIT#jit-opcache-jit-values I tried both too :

tracing: An alias to the granular configuration 1254.
function: An alias to the granular configuration 1205.

And it works too if you don't want to use 1255. But I used 1255 because on this Pull Request I seen lot of Unit Tests with 1255 configuration.
