From phpinfo I see: On problematic CentOS 7.x: PDO Driver for MySQL enabled Client API version mysqlnd 5.0.12-dev - 20150407 - $Id: 7cc7cc96e675f6d72e5cf0f267f48e167c2abb23 $ Which is very very old. On my develop machine (it works well) is: PDO Driver for MySQL enabled Client API version mysqlnd 7.4.6 Another test look onCentOS good when I use: PDO::ATTR_EMULATE_PREPARES = true; ------------------------------------------------------------------------ [2021-04-20 04:37:30] standus at post dot cz I replaced PDo with mysqli library and its same problem. It look like some middleware centos library between php and madiadb is wrong. ------------------------------------------------------------------------ [2021-04-16 08:57:47] standus at post dot cz Somebody has similar problem too. https://laracasts.com/discuss/channels/laravel/pdo-hangs-on-executing-query-on-heavy-queue-system-timeout-does-not-work ------------------------------------------------------------------------ [2021-04-15 07:37:01] standus at post dot cz On PHP 8.x its same problem. ------------------------------------------------------------------------ [2021-04-14 20:55:01] standus at post dot cz I have very similar big problem which I reported here. https://jira.mariadb.org/browse/MDEV-25414 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
