# vi bitrix/.settings.php
заменить
       'className' => '\\Bitrix\\Main\\DB\\MysqlConnection',
на
       'className' => '\\Bitrix\\Main\\DB\\MysqliConnection',

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

Проверить чтобы стоял модуль php-mysqlnd:

# rpm -qa | grep mysqlnd
php-mysqlnd-7.0.6-3.el6.remi.x86_64
