At times if I look at Home, and one of the workstations is under the red X. I take a look and this is the error that I see alot:

Bundle Bundle.ItemCreationError Bundle.ItemCreationError{445bb7d79dcd45bfb444f8eda d11b2e4;Object reference not set to an instance of an object.

What could be causing this error?
ZCM 10.3.2
