Hi, Zoltan -

That superficially sounds to me like the case of someone on the
client end having experimented with a newer level of the TSM client,
and then having dropped back to the prevailing older value, leaving
the newly deposited data in the TSM storage pools with advanced
control data and structures.  This might also happen when some other
client, which happens to be at the higher level, poses as that other,
older client, via -VIRTUALNodename.
