Jobs are intended for executing of tasks in the background. They handle operations like sending notifications, mass mailing, syncing, cleanup, etc.

Scheduled Jobs

Scheduled Jobs are intended for recurring job execution. Scheduling for a specific job can be configured by the administrator, using a crontab notation.

* * * * *
| | | | |
| | | | |
| | | | +---- Day of the Week   (range: 1-7, 1 standing for Monday)
| | | +------ Month of the Year (range: 1-12)
| | +-------- Day of the Month  (range: 1-31)
| +---------- Hour              (range: 0-23)

If you want a job to be run as often as possible you need to set the scheduling to * * * * *.

Setting up

There are two ways how jobs can be processed: with crontab or daemon.


Cron is easy to configure. It's supported by most of hosting providers.

See how to configure cron here.

In Unix systems cron is supposed to be run not more often than once a minute. It's possible to overcome this limitation with the following trick.

Add multiple lines in crontab with delays in seconds:

* * * * * /usr/bin/php -f /var/www/html/espocrm/cron.php > /dev/null 2>&1
* * * * * sleep 15; /usr/bin/php -f /var/www/html/espocrm/cron.php > /dev/null 2>&1
* * * * * sleep 30; /usr/bin/php -f /var/www/html/espocrm/cron.php > /dev/null 2>&1
* * * * * sleep 45; /usr/bin/php -f /var/www/html/espocrm/cron.php > /dev/null 2>&1

Note that command that runs cron differs depending on server environment.


Command to start daemon using nohup:

nohup php /path/to/espocrm/daemon.php &

Configuration for using systemd:

Description=EspoCRM Daemon Service

ExecStart=/usr/bin/php /path/to/espocrm/daemon.php


Requires pcntl and posix extensions, php 7.1 or later. Windows is not supported.

Recommended to turn on processing jobs in parallel processes: Administration > Scheduled Jobs > Jobs (top-right corner) > Settings (top-right corner) > Jobs Run in Parallel.

Running jobs in parallel processes

By default jobs are executed one by one that may cause situations when one job blocks the execution of the next job for some time (usually it's not more than one minute). To avoid this, it's possible to run jobs in parallel processes. The parameter is available at Administration > Scheduled Jobs > Jobs in the top-right corner > Settings in the top right corner.

Available since version 5.5.0.

Requires pcntl and posix extensions, php 7.1 or later. Some server configurations may restrict the ability to run child processes.

Windows is not supported.
