Question

I’ve assigned the memory limit of php to 999m so it appears in phpinfo like

memory_limit 999M 999M

when I use phpinfo(); to show it.

Unfortunately when I try to run a fairly large script, it seems like the limit is 256M

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 40 bytes) in /xxx/wp-includes/wp-db.php on line 1403

Anyone have any ideas why or what I can do to increase the limit (and have it actually work)

If it helps I’m running centos5 32bit and with php running in fcgi mode

Answer 1

Create a php file called test.php, put inside:

<?php
phpinfo();
?>

Check for “Configuration File (php.ini) Path” and “Loaded Configuration File” to see the correct php.ini path.
Edit php.ini and search for memory_limit and set it to:

memory_limit = 999M

Check if you have more than one occurrency of memory_limit into the php.ini file. In the case, delete it.

Stop apache, and then restart it (apachectl restart | apachectl graceful | kill -1 are not ok. Stop, then start).

Recheck test.php to see if the new parameter got acquired.
