[notice] child pid 23145 exit signal Segmentation fault (11), possible coredump in /tmp

But nothing found under /tmp

How can i find the error?

Coredumps are to be inspected with a debugger. They are not very useful usually. (Unless you develop a PHP module, which could have caused the fault.) – Spearman

Answer 1

Endless loop of the function in PHP code caused this error.

Answer 2

Check whether your PHP-FPM and PHP versions match. Make sure there is a (correct) PHP-FPM configuration corresponding to your PHP and PHP-FPM version, respectively.

PHP-FPM (config in /etc/php/7.0/fpm) and PHP versions may have gotten out of sync while updating. Updated PHP (/etc/php/7.3/) may cause apache child segfaults because of missing PHP-FPM configuration in /etc/php/7.3/.
