of course. the server has:

The client has an older 2.7.x firmware. Mostly because of
the X58 chipset incompatibility with newer firmwares. Your
question suggests that this behaviour may be related to the
older firmware. So I changed the client side test to another
host with newer firmware. Nevertheless the TSO problem
occurs there too.
