This does not seem like some common error, so I would say Support help is required.
Please provide a support case ID for this issue, as requested when you click New Topic.
We have seen this issue previously (v9.5 U4) - offload resume misbehaves, as the result a task fails. But it should have been fixed long time ago (v11). So kindly keep working with the support team on finding the reason why the issue re-appears. Thanks!
