 +==== Increase pm.max_children ====

 +PHP-fpm has a maximal amount of children processes which it uses to serve requests. The default setting of 5 most propably is too low for almost any kind of server. Check for similar messages in your log /var/log/php7.3-fpm.log<code>

 +[05-Mar-2019 13:01:21] WARNING: [pool www] seems busy (you may need to increase pm.start_servers, or pm.min/max_spare_servers), spawning 16 children, there are 3 idle, and 40 total children

 +To change it edit /etc/php/7.3/fpm/. The following values are no recommendations in any way. I've just copied it from a server, with relatively low load. You have to consider the expected amount of requests, but also your server resources, especially the memory.
