Hi,
When I check the php7.4-fpm.log, I can see that there are lots of exited on signal 11 (SIGSEGV - core dumped) warnings. Sametime I can see Nginx 502 bad gateway error. I followed the WordOps community this solution but it is not fixed.
PHP Version 7.4.25
nginx version: nginx/1.21.3 (VirtuBox Nginx-ee)
Please help me to fix this error.
