XML document structures must start and end within the same entity.

I am getting the following error intermittently for some reviews from ccollab.  Incidentally these reviews can take forever to come up.  Have anyone else seen this?

ccollab admin review-xml 1 --xpath //reviews/review
[Fatal Error] :3:22: XML document structures must start and end within the same entity.
