Theirry, are you willing to try to see if you can get a reliable
reproduction case?  That's what we need, very badly.  The fact that
you only copied 20GB is very good; better than than 2TB.  If you can
reliably reproduce the failure 2 or 3 times, can you give us exact
reproduction instructions?  That would be extremely useful.

Thanks in advance,
