> [@ison](#): > > Column change will be processed in background job Interesting… what background job is it referring to - Mautic or Database? If Mautic, I wonder which task would need to be called via cronjob. ---

I checked the translations, and I couldn’t find any related output. Similar text is visible, when you import… ---

Can it be related to PHP 8 ? Mautic 4 does not support PHP 8. In Mautic 4.4.8 I created a couple of days ago a Custom Field, without any issue. ---

Hello @dirk_s, thanks for your reply. To be honest I don’t know which background job it is referring to. this is the cron job that I use: 0,10,20,30,40,50 \*/1 \* \* \* /usr/bin/php /var/www/html/bin/console mautic:segments:update --env=prod \> /dev/null 2\>&1 2,12,22,32,42,52 \*/1 \* \* \* /usr/bin/php /var/www/html/bin/console mautic:campaigns:update --env=prod \> /dev/null 2\>&1 4,14,24,34,44,54 \*/1 \* \* \* /usr/bin/php /var/www/html/bin/console mautic:campaigns:trigger --env=prod \> /dev/null 2\>&1 6,16,26,36,46,56 \*/1 \* \* \* /usr/bin/php /var/www/html/bin/console mautic:broadcasts:send --env=prod \> /dev/null 2\>&1 8,18,28,38,48,58 \*/1 \* \* \* /usr/bin/php /var/www/html/bin/console mautic:emails:send --env=prod \> /dev/null 2\>&1 ![image](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/1/1edc8f52aac7589b7dae1ad27c1e00c5826e165e.png) ---

I doubt, that any of those cron jobs will work on the database structure… I’d suggest to open an issue in github for that and giving as much related information as possible. Usually adding a custom field is no issue even in larger installations. Is you server environment well sized? At least 500MB of RAM, better more? What happens if you try to add another custom field? By the way - little improvement: I would suggest to setup one cron job that starts the commands in squence: [How to setup Mautic cron jobs](https://twentyzen.com/en/think/faq-items/start-mautic-cron-jobs-in-sequence/) … this allows faster processing. ---

You’ve probably configured to create the custom fields in a background job. It’s needed for bigger database sizes because it can take a long time. See [Manage custom fields | Mautic](https://docs.mautic.org/en/contacts/manage-custom-fields#creating-custom-fields-via-a-command) ---

@escopecz thanks for pointing this out! This is a great little trick as often on big databases we have timeouts when creating new fields. ---
