title: "Fatal error: Allowed memory size of" error on RedHat/Centos 7.5 when I install Drupal
body: <p>I installed a LEMP stack on a Centos 7.5 to run a Drupal application.</p>
  
  <p>PHP version needed is 7.2, installed using epel/remi repositories.</p>
  
  <p>When all is done, and the application is correctly deployed, I get a "Fatal error: Allowed memory size of XX bytes exhausted (tried to allocate XXX bytes) in bla/bla/bla.php"</p>
  
  <p>It seems to be a memory_limit issue, but it cannot be: PHP memory limit is set to 512M and the application runs correctly in any other environments (based on Debian). I tried also to reproduce this issue re-creating the stack on a centos:centos7.5 docker image, and all works well.</p>
  
  <p>I think this could be a RedHat/Centos issue, maybe some OS parameters. Consider that I've also disabled Selinux.</p>
  
  <p>Any idea?</p>
  
  <p>Thx
  Daniele</p>
