Do you know what is the reason for this catastrophic error? 
most of the time, when you will get this event your CQ is in error (CQ overrun).

You will get an affiliated event + completion with error.

I don't familiar with the SDP code, but as much as i know the module that handles
the IB resources should set the async event handler for all of it's resources
to know what is the state of them (for error and notification events).
