SCCM 2012 - Collections not evaluating

Had an interesting issue relating to collections that were not evaluating. The hourglass of despair was rolling around on all the collections.

A quick look through the colleval.log and there was an error:

[Auxiliary Evaluator] Error refreshing collection, will retry momentarily [xxxxxxxx, Error 0xb]

xxxxxxxx being the collection ID.

In my case the collection was a direct membership rule that was assignment to an 'x64 unknown computer' on the specified collection. Once I removed the direct membership rules then the collections could be evaluated and populate the collections.
