    If the file is php then yes caching could be Zend Opcache related, the default revalidate frequency is 180 seconds
    Code (Text):
    php --ri 'Zend OPcache'

    You can exclude a file or path from Zend Opcache caching completely via blacklist option too
    To customise Zend Opcache settings see the instructions to create your own .ini settings file to retain the changes at https://centminmod.com/phpfpm.html#customphpini

    Example order of php .ini files applied via php --ini command
    Code (Text):
    php --ini
    Configuration File (php.ini) Path: /usr/local/lib
    Loaded Configuration File:         /usr/local/lib/php.ini
    Scan for additional .ini files in: /etc/centminmod/php.d
    Additional .ini files parsed:      /etc/centminmod/php.d/a_customphp.ini,
    /etc/centminmod/php.d/curlcainfo.ini,
    /etc/centminmod/php.d/geoip.ini,
    /etc/centminmod/php.d/igbinary.ini,
    /etc/centminmod/php.d/imagick.ini,
    /etc/centminmod/php.d/mailparse.ini,
    /etc/centminmod/php.d/memcache.ini,
    /etc/centminmod/php.d/memcached.ini,
    /etc/centminmod/php.d/redis.ini,
    /etc/centminmod/php.d/zendopcache.ini

    If i want to override opcache.revalidate_freq 180 seconds default, I'd create a .ini file after /etc/centminmod/php.d/zendopcache.ini alphabetically i.e. /etc/centminmod/php.d/zzendopcache.ini

    So ordered after zendopcache.ini
    Code (Text):
    php --ini
    Configuration File (php.ini) Path: /usr/local/lib
    Loaded Configuration File:         /usr/local/lib/php.ini
    Scan for additional .ini files in: /etc/centminmod/php.d
    Additional .ini files parsed:      /etc/centminmod/php.d/a_customphp.ini,
    /etc/centminmod/php.d/curlcainfo.ini,
    /etc/centminmod/php.d/geoip.ini,
    /etc/centminmod/php.d/igbinary.ini,
    /etc/centminmod/php.d/imagick.ini,
    /etc/centminmod/php.d/mailparse.ini,
    /etc/centminmod/php.d/memcache.ini,
    /etc/centminmod/php.d/memcached.ini,
    /etc/centminmod/php.d/redis.ini,
    /etc/centminmod/php.d/zendopcache.ini,
    /etc/centminmod/php.d/zzendopcache.ini


    In /etc/centminmod/php.d/zzendopcache.ini add value say 10 seconds
    Code (Text):
    opcache.revalidate_freq = 10


    Note though reducing revalidation frequency lowers performance of caching all the time 24/7. Best way is just to restart php-fpm and nginx after file updates which are done manually via command shortcut
    Code (Text):
    nprestart

    After restart recheck value is now at 10 seconds
    Code (Text):
    php --ri 'Zend OPcache'

    opcache.file_cache_only => 0 => 0
    opcache.file_cache_consistency_checks => 1 => 1
    opcache.huge_code_pages => Off => Off

    Any php related setting can override and customised this way as well :)
