    Hello,
    supporting a server with Plesk 12.5 on Centos 7.

    A number of domains ( ~100 ) are using plesk-php56-fpm, and in their pool definition ( /opt/plesk/php/5.6/etc/php-fpm.d/thedomain.tld.conf ) there is a line referring to xCache :

    [....]
    ; Uses for log facility
    ; If php_value[error_log] is not defined error output will be send for nginx
    catch_workers_output = yes

    ; php.ini custom configuration directives
    php_value[date.timezone] = europe/athens
    php_value[xcache.cacher] = on
    php_value[open_basedir] = "/var/www/vhosts/thedomain.tld/:/tmp/"

    ; Following directives override default pool configuration
    pm.max_children = 20​

    I have identified the timezone coming for the UI (PHP "Additional Directives") from the subscription, and the open_basedir pattern is from the domain. The override in the pool configuration in the last line come from /var/www/vhosts/system/thedomain.tld/conf/php.ini

    However, for the life of me, I cannot find any reference to xCache anywhere in order to disable it, and it's spamming my main log ( /var/log/plesk-php56-fpm/error.log ) with tons of the line

    [12-Jan-2017 02:54:42] WARNING: [pool thedomain.tld] child 3918 said into stderr: "ERROR: Unable to set php_value 'xcache.cacher'"​

    All of the domains were migrated from an older Plesk installation and defaulted to PHP5.4 which did have xCache, and then switched over to PHP5.6 if that makes any difference.

    I have obviously changed / added things to the vhost php.ini, and have run /usr/local/psa/bin/php_settings -u - the generated file contains the above line.

    Any ideas / leads as to where I should look next?
    Thanks in advance!

    Type the following command to verify XCache software on your PHP5.6:

    # /opt/plesk/php/5.6/bin/php -v

    If you have enabled Xcache, you should see something like

    # /opt/plesk/php/5.6/bin/php -v

    ........

    If no - how your directive php_value[xcache.cacher] = on can be handled?

    Hello IgorG,
    no, PHP56 does not have (nor should it in my humble opinion) xCache - it comes with OPCache.
    I am trying to figure out HOW the setting gets there so I can remove it (and stop the error messages), ie where that config value is actually stored and get aggregated into the pool file.

    root@myserver:/ # /opt/plesk/php/5.6/bin/php -v
    PHP 5.6.29 (cli) (built: Dec 9 2016 12:07:26)
    Copyright (c) 1997-2016 The PHP Group
    Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
    with the ionCube PHP Loader (enabled) + Intrusion Protection from ioncube24.com (unconfigured) v5.0.18, Copyright (c) 2002-2015, by ionCube Ltd.
    with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies
    XCache IS present on PHP54 though
    root@myserver:/ # /opt/plesk/php/5.4/bin/php -v
    PHP 5.4.45 (cli) (built: Mar 25 2016 17:04:14)
    Copyright (c) 1997-2014 The PHP Group
    Zend Engine v2.4.0, Copyright (c) 1998-2014 Zend Technologies
    with XCache v3.2.0, Copyright (c) 2005-2014, by mOo
    with the ionCube PHP Loader (enabled) + Intrusion Protection from ioncube24.com (unconfigured) v5.0.18, Copyright (c) 2002-2015, by ionCube Ltd.
    with XCache Cacher v3.2.0, Copyright (c) 2005-2014, by mOo​

    so I am giving the possibility that the domains were at some point using PHP54, got the setting, moved to PHP56 and did not lose it? I do not know.

    The server also has PHP70 (which also only has OPCache). All sites are using FPM or FastCGI ( mod is not enabled ). Let me know if I can provide any other detail to help you have a clearer picture!

    Again, thanks in advance!

    It is because of:

    [root@ppu17-0 etc]# ll /opt/plesk/php/5.4/etc/php.d/40-xcache.ini
    -rw-r--r-- 1 root root 3112 Oct 6 2015 /opt/plesk/php/5.4/etc/php.d/40-xcache.ini
    [root@ppu17-0 etc]# rpm -qf /opt/plesk/php/5.4/etc/php.d/40-xcache.ini
    plesk-php54-xcache-3.2.0-centos7.15100614.x86_64

    For php versions 5.5+ we use opcache instead of xcache.

    The domains with the problem though all use PHP56 though -- why is this directive appearing in those pools?

    root@myserver:/opt/plesk/php# grep -R xcache *
    5.4/etc/php.d/40-xcache.ini: [xcache-common]
    [... many other entries from the same file omitted ..]
    Binary file 5.4/lib64/php/modules/xcache.so matches
    5.6/etc/php-fpm.d/domainA.com.conf: php_value[xcache.cacher] = on
    5.6/etc/php-fpm.d/domainB.com.conf: php_value[xcache.cacher] = on
    [.. one entry per domain in the php-fpm.d dir with that line ..]
    root@myserver:/opt/plesk/php#

    Perhaps it is consequences of migration from hosting with php5.4

    I think it's a leftover as well, where would I search to remove it though? When regenerating the pool files ( in /opt/plesk/php/5.6/etc/php-fpm.d ) it still adds the xcache line, and I am trying to figure out where it comes from in order to remove it.

    I'd suggest you check carefully:

    1. handler's php.ini
    2. Service Plan, PHP Settings in Plesk UI
    3. Overrride file /var/www/vhosts/system/thedomain.tld/conf/php.ini

    Assuming handlers
    - php.ini is /opt/plesk/php/5.6/etc/php.ini ( no reference to xcache )

    root@myserver:/opt/plesk/php/5.6/etc# grep xcache php.ini
    root@myserver:/opt/plesk/php/5.6/etc#

    - service plan -> php tab -> "additional php directives" only has the "timezone = europe/athens" line (see attached )
    - the per vhost php.ini only contains fpm directives ( setting pm.max_children nothing else )

    root@myserver:/var/www/vhosts/system/domainA.com/conf# cat php.ini
    [php-fpm-pool-settings]
    pm.max_children = 20
    root@myserver:/var/www/vhosts/system/domainA.com/conf#

    THANK you for your assistance up to now, however the above do not have any reference to this.
    Any other ideas?

    Nice one - although I cannot see which version is which, xcache params are shown numerous times :

    Code:

    Hello IgorG, and thanks for your continued efforts!

    Unfortunately I do not even have that file, and no matches for xcache exist in that subtree :
    Code:
    root@myserver:/usr/local/psa/admin/conf# ls -lah

    root@myserver:/usr/local/psa/admin/conf# grep -R xcache *
    root@myserver:/usr/local/psa/admin/conf#
    Going up that tree though there are a few matches in /usr/local/psa/admin/externals/Zend/Cache/Backend/Xcache.php however that code is simply usage of xcache if it is loaded.
