The output was all what I found in the morning after a greater number
of vos move. So no, it does not happen "often". As this volume takes
about 100 minutes to move (probably because of the great number of
files involved), testing is not very practical. (333 files/sec,
1.4MB/sec). Other volumes with less files move at 20-30MB/sec.

There was nothing lingering any more when I was looking later.
