but the above statement  is contradicting the statement from the IB specs
"For QPs:
• For Affiliated Asynchronous Errors, it may not be possible to con-tinue
to process Work Requests. In this case, outstanding Work
Requests will not be completed.
• When handling the error notification, it is the responsibility of the
Consumer to ensure that all error processing has completed prior
to forcing the QP to reset. " (p.no 461 vol-1.2)

what i can understood from the above statement is,  no completion will be generated for the workrequest which is in progress when an affliated asynchronous error occured.

if there is no completion from where SDP will poll???
