Hi! According to my very little experience with huge packages, I think that even that value is rather big. We are running with 9000 here. About 20 years ago we had a printing problem when some packet buffer was a few bytes to small: Small print jobs would work, but lerger ones won't. Maybe you are seeing similar with iSCSI. Also: Have a _matching_ MTU along the whole path.
