Yes, you are. When the QP state is being changed to the Error (because 
of a real error or by the user)
all of the outstanding WRs should be flushed with error for this QP.

You didn't specify which HW you are using, but maybe you should ask for 
a FW/SW upgrade for the
HCA that you are using, this may solve your problem.
