    I have the exact same issue Ian.

    I have multiple XenServers connected to OmniOS storage units. Under
    specific circumstances, I get iscsi disconnects which prove fatal for the
    XenServer host guests. These machines run a mixed bag of ConnectX and
    ConnectX-2 cards

    I have managed to get the system stable, but with severe compromises.

    Previously using 10Gb cards, I didnt have any problems what so ever.
