# Strange memory usage

 * I’m running WP with Woocommerce and a few plugins including wp-piwik. I have 
   Nginx running as reverse proxy and implementing SSL. Periodically I’m getting
   504 Bad Gateway errors. These occur in both the admin panel and the front end.
   In a recent instance, the Nginx log contained this;
 * 2017/01/11 06:56:07 [error] 25260#25260: *5697 FastCGI sent in stderr: “PHP message:
   PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate
   140701003375704 bytes) in /var/www/wp-content/plugins/wp-piwik/wp-piwik.php on
   line 33” while reading response header from upstream, client: 96.47.239.2, server:
   dev.my-server.com, request: “GET /wp-admin/admin-ajax.php?action=woocommerce_mark_order_status&
   status=processing&order_id=6616&_wpnonce=71e076ae15 HTTP/2.0”, upstream: “fastcgi://
   unix:/run/php/php7.0-fpm.sock:”, host: “dev.my-server.com”
 * Searching has found many cases where people are running out of memory, but where
   the alloction request was small. I’m seeing a huge allocation request. Is this
   correct, or is it being falsely reported?
 * For now I’ve upped the memory limit for PHP to 256MB and restarted PHP, but I’d
   like to understand the underlying problem. How can I best troubleshoot this?

 * I suggest that you try contacting the developer of the wp-piwik plugin about 
   this issue as it seems that it is this plugin that is making the memeory call.

 * I don’t believe that the plugin is at fault here. In another occurance I have
   this;

 * The attempted alloaction just can’t be right. At the very least, there’s got 
   to be a serious bug somewhere that’s causing misreporting on memory allocation
   requests.
