In large or medium-sized projects, sometimes there is an issue with the transfer of especially heavy agents to Cron.

  • First, fully disable execution of agents on a hit. To do this, the command /bitrix/admin/php_command_line.php?lang=ru should be executed in PHP-console of Bitrxi24 product administrative menu:
    COption::SetOptionString("main", "agents_use_crontab", "N"); 
    echo COption::GetOptionString("main", "agents_use_crontab", "N"); 
    COption::SetOptionString("main", "check_agents", "N"); 
    echo COption::GetOptionString("main", "check_agents", "Y");

    As the result, we should have NN.

  • Remove the definition of the following constants from the /bitrix/php_interface/dbconn.php file:
    define("BX_CRONTAB_SUPPORT", true);
    define("BX_CRONTAB", true);

    And add:

    if(!(defined("CHK_EVENT") && CHK_EVENT===true))
       define("BX_CRONTAB_SUPPORT", true);
  • Next, create agent verification and system messages multicasts file /bitrix/php_interface/cron_events.php:
    $_SERVER["DOCUMENT_ROOT"] = realpath(dirname(__FILE__)."/../..");
    define("NO_KEEP_STATISTIC", true);
    define('CHK_EVENT', true);
    define("BX_CRONTAB_SUPPORT", true);
    define("BX_CRONTAB", true);
  • And add this script into Cron:
     */5 * * * * /usr/bin/php -f /home/bitrix/www/bitrix/php_interface/cron_events.php

After that, all agents and forwarding of system Messages will be processed under cron, once each 5 minutes.

The parameter responsible for the quantity of e-mail messages, processed at once, is required to be modified to prevent the increase of e-mail messages queue. To do that, execute the following command in PHP-console:

COption::SetOptionString("main", "mail_event_bulk", "20"); 
echo COption::GetOptionString("main", "mail_event_bulk", "5");
