"QueueManager is inactive" error when making changes to a model
This item has been identified as an outstanding known issue as of the 16 June, 2018 platform release; a workaround is provided until the issue is officially fixed. Please contact Support at firstname.lastname@example.org immediately if you encounter this issue.
Attempts to close and reopen the import dialog will continue to fail with the error:
Failed to read data: QueueManager is inactive
The source model of the import will also be affected and continue to display the same error when trying to make any changes to it.
Please contact email@example.com if you encounter this problem.
You can attempt to close the source and target models via Model Management but if this fails Support can help resolve the issue.
To avoid seeing the problem again, when opening the import dialog for a model to model import, avoid clicking other tabs in the import dialog until the data preview has loaded in each.
