Hi Johan, That's what I initially suspected, and so I ran a small test to output the relationship in question, and there is only one.
But wouldn't the same error occur when using a single thread, if there were more than one relationship of the same type and I invoked getSingleRelationship... If it helps at all I'm running on winxp 64bit. I'm going to try to replicate the issue with using a small sample and if I can, would it be helpful to send it you?
