!!!Рішення:
#
Замінити # в  bitrix/.settings.php
       'className' => '\\Bitrix\\Main\\DB\\MysqlConnection',
на
       'className' => '\\Bitrix\\Main\\DB\\MysqliConnection',

# та bitrix/php_interface/dbconn.php
Добавити:
define( "BX_USE_MYSQLI" , true);

Перевірити щоб був встановлений модуль -  php-mysqlnd:
# rpm -qa | grep mysqlnd
php-mysqlnd-7.0.6-3.el6.remi.x86_64
