Ubuntu 14.04, Plesk 12.5 with 5.6.15 FPM it is not possible to allocate more as 300MB opcache memory

[cij]

Hello,
I try to allocate more opcache memory for php-fpm 5.6.15, but currently I cannot give more than 300 MB. Is there any restrication because if I change the memeory setting to 301 MB the webserver service is not starting after saving the php.ini.

Current setting:
opcache.memory_consumption=300

Can anyone help with this issue?

Many thanks in advance

Technically, there is no limit.

Theoretically, it is not adviceable to exceed the default (64MB) with a large amount: try 128MB or 192MB.

Practically, opcache.memory_consumption=300 only makes sense if other relevant variables are set accordingly.

In summary, I can keep it short: use a lower value.

To satisfy your curiosity: have a look at the maximum amount of memory that is assigned to the application (see PHP settings on the domain), I bet it is 300MB or lower.

Regards.....
