The first attempt to load Zabbix dashboard ends with 500 Error

The second attempt and all others proceed without any problem.

The problem can be solved by disabling Opcache. (opcache.enable=0)

As you see this is Opcache issue.
Nevertheless instead using Opcache better switch to nginx and php-fpm. Instead 10-15% improved performance you will have +2 times faster webfrontend.

I reported it on the our bug tracker. For details look at ZBX-16117.
