ERROR PHP : Allowed memory size of 2097152 bytes exhausted (tried to allocate 32768 bytes)

All,

Cacti has been running fine with no issues, the server was then rebooted and now Im getting an Error 500 trying to access the Cacti GUI, looking into the cacti.log file each time a user tried to access the GUI this is coming up in the logs.
ERROR PHP : Allowed memory size of 2097152 bytes exhausted (tried to allocate 32768 bytes)in file: /var/www/html/cacti/include/global_arrays.php on line: 269.

The memory_limit in the /etc/php.ini file is set to 512MB so Im not sure what is going on here?

Any help as always is appreciated.

Chris

Another server reboot seems to have resolved this, not sure what the initial issue was
