We just ran January updates on our production servers. After the update, I have a test workflow that I use to see if anything is broken. That workflow ran fine. This morning, I came into work with hundreds of workflow error messages. I keep getting the Workflow Failed to Start, Cancelled by System Account. Also, when I attempt to publish, I get a failed to publish error. This appears to only be affecting one Site Collection. My test workflow is in a different site collection and that workflow still runs fine.
I haven’t seen anything that would affect one site collection and not another.
All workflows (list and site) are failing in the one site collection.
