Pre-analysis shows that persistence engine was requested to store a document, and internal table had a file revision of 0 to relevant vbucket.
This is clearly violation of invariant, since fileRev in data/$bucket/$vbid.couch.$fileRev is numbered with 1 and is ever-growing.
On a first glance, invariant is carefully maintained.
Yet it somehow got violated in our setup.
