After migrating from version 5.9.5 to 6.0, we recomputed initial statistics and noticed that stats showed repository had almost doubled. Number of documents didn't changed. We reverted to 5.9.5 and recomputed stats again. All numbers went back to normal.

After some testing, we've noticed that each time we recompute initial statistics, calculated size of documents is increased. It seems as if cleanup of previous stats is not working properly.

We also tested Nuxeo 7.1 and obtained the same results as with 6.0.

Has anyone experienced the same behaviour?
