If the QP was the responder of an RDMA operation which failed, there should be an async event on the QP.

In case of an error, the QP state will be changed to error and all the WR (in SQ and RQ) will be flushed (with error)

where does it  happen? in the interrupt handler or ??
i have gone through the mthca code 
    1. there is no IQE or event corresponding to the connection lose
    2. in the interrupt handlers only the event handler corresponding to      that QP  is called (no  QP  state change)
