    Hello @Gojko,

    I recommend searching the PHP-FPM error logs (/opt/cpanel/ea-php$$/root/usr/var/log/php-fpm/error.log) for any domain name's reaching the max_children limit. You'd replace ea-php$$ with each specific version of PHP (e.g. ea-php70) that PHP-FPM is utilized with on your system. The offending entries will look like this:

    Code:
    ERROR: unable to read what child say: Bad file descriptor (9)
    NOTICE: [pool domain_tld] child 1234 exited with code 0 after 25.12345 seconds from start
    If you find specific domain names are reaching the limit, you can increase the max_children value for them using the "Pool Options" feature in "WHM >> MultiPHP Manager".

    Thank you.

    Thank you for the replay.
    I found something:
    Code:
    [09-May-2018 19:32:56] WARNING: [pool domain] child 7398 said into stderr: "zend_mm_heap corrupted"
    [09-May-2018 19:32:56] WARNING: [pool domain] child 7398 exited with code 1 after 0.378050 seconds from start
    [09-May-2018 21:11:25] WARNING: [pool domain] child 734 exited on signal 11 (SIGSEGV) after 0.123760 seconds from start
    is that?
    what is with "zend_mm_heap corrupted" or "exited on signal 11 (SIGSEGV)"?
    if i increase max_children it will fix this?

    Hello @Gojko,

    Do you happen to have OPCache enabled as a PHP extension? If so, please let us know the output from the following command:

    Code:
    grep opcache.fast_shutdown /opt/cpanel/ea-php*/root/etc/php.d/*opcache.ini
    I've seen reports where disabling the fast_shutdown option in the opcache.ini file and then restarting Apache solves this error message.

    Thank you.
