  • Opcode cache Event ID 487 issue of PHP 7.x

    Jan 30, 2019 08:52 AM|stone.pei|LINK

    Hi, it's seems that the OpCode cache was removed from wincache 2.0,  that means we need to use the PHP Zend Opcache? 

    while seems that on PHP7.2 , I always hit the error: 
    The description for Event ID 487 from source Zend OPcache cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
    I saw someone said that set 

    ;opcache.mmap_base="0x20000000"

    but it doesn't works. 

    Any idea ?

    HI ALL 

    I found a solution for this issue. 

    1)  disable the windows ASLR feature with  EMET

    2)  set opcache.mmap_base="0x20000000" in php.ini,  seems no this kind of issue at all .
