   ago i run well with 512mb of memory limit.
 * now i got problems when updating plugin and main-core online.
    few data: server
   under Nginx and php_FPM for fastCGI
 * This is an istance of WP… 300Mb!!!!

 * When updating a single plugin i get:
 * > [error] 1657#0: *183 FastCGI sent in stderr: “PHP message: PHP Fatal error:
   > Allowed memory size of 536870912 bytes exhausted (tried to allocate 130968
