Hello,
Just a quick question: What is the maximum amount of memory that you allow for a PHP process?
Fyi, some hosting providers set the default maximum amount of memory for PHP is 128MB on all of their servers. However this can be overrode by using a custom php.ini or .htaccess as long as the value is not set above 500MB and does not interfere with the performance of the server.
