Ideally, you would provide a short, self containted example[1], or at least a backtrace with debug symbols[2].

The loaded extensions are unlikely to be an issue per se, but PHP 7.3.29 is no longer actively supported. Please check with PHP 7.4.22 or 8.0.9. ------------------------------------------------------------------------ [2021-08-03 21:01:56] kontakt at xlu dot pl PHP v 7.3.29 php -m [PHP Modules] Core date imap json libxml mbstring mysqlnd pcre PDO Reflection session SPL standard [Zend Modules] ------------------------------------------------------------------------ [2021-08-03 10:18:31] cmb@php.net Okay, thanks for clarification. So the connection error is unrelated to the segfault which happens during shutdown. Can you reproduce this with any of the actively supported PHP versions[1]? If so, please list all enabled extensions (php -m).
