I really cannot tell what has been configured to get this behaviour and I hope you have some additional ideas on where to look into this to check which job updates the tickets. I cannot find any cronjob that’s responsible for this behaviour. There is only a root crontab and no user crontab in the system.
I think you have an automation created?
Go to one of these tickets and click on the right top of „ticket“ and gehen „history“. Now you can See which task edited the ticket
This is most likely happening because of the new year in connection with configured SLAs.
Background information:
Once per day, usually at or around midnight, Zammad synchronizes its calendar. On New Year’s Day, new holidays are imported. With new holidays in the calendar, all tickets for which an SLA is configured, have to be recalculated. This is technically an update to the ticket, and is therefore shown as one on the UI.
Thank you for your answer. We see this behaviour since more than a half year now. So it’s not something in combination with the new year. However SLAs is a good hint. I’m not using my SLAs, so I turned that off. I’ll check if that helps.
Ah, sorry. My bad. I just saw the title, and in conjunction with the new year having just started, I assumed that it’s this known thing.
It’s still not unlikely that it’s the SLAs. One way to check this would be from the rails console with the following command:
Ticket.find(<ticket_id>).preferences
Where <ticket_id> should be replaced with the ticket-id of one of the tickets that show as updated. You can find the ticket-id by looking in the URL-bar of your browser when that ticket is openened. The number at the end (eg. the 123 in: #ticket/zoom/123) is the ticket-id.
Look for a key called "calendar_updated_at". If it corresponds with the update time that the UI is displaying for this ticket, then it’s most likely an SLA recalculation.
15:35 UTC is my 16:35 or rounded 16:36 GMT+1, interesting. There should not be a calendar update every 1-2 weeks. I’ll wait for the next event, when that happens, or the SLA deletion turned that behaviour off.
