Issue
Cause
The workflow was triggered in the middle of an instance upgrade. The timer finished 10 seconds after the upgrade completed.
Resolution
During an upgrade, the instance is under maintenance and many jobs and processes will be halted until the upgrade is complete. Please note that this is expected behavior and should be considered when planning an instance upgrade.
It is highly advised against initiating a workflow during an upgrade process, particularly when the workflow contains timer activities. This is because the upgrade may interfere with the timer's functionality, leading to unpredictable results. To avoid such issues, it is strongly recommended to schedule the upgrade during off-hours when there is minimal user activity.
This proactive approach ensures a smoother upgrade process and reduces the risk of workflow disruptions.
