Seems like this is some timing issue.

Comment 3 Van Halbert 2011-01-20 16:25:03 UTC 
Per engineer (and in TEIID-1445):   This should only occur with dynamic vdbs, and only if the source metadata load cannot be loaded from cache. If the error occurs the workaround would be to redeploy the vdb or restart the server. The fix is to make access to the model problem / validity checking thread safe.
