They installed 2 VM (FreeBSD 9.2 with the customized FreeBSD kernel) on Azure. Network went offline very soon when the big file (~320M byte) is copied from one VM to anther through "scp".

It is supposed 9.2 allows the back-ported Hyper-v drivers from 10. Is this assumption correct? > Hi! > > It may be something to do with maximum mbufs per packet or some other > limit like that.
