[openib-general] Local QP operation error

[Ramachandra K]

In a kernel module, on polling the CQ, I am getting a local QP
operation error (IB_WC_LOC_QP_OP_ERR). Work request
posted was of type IB_WR_SEND and the QP was moved to
IB_QPS_RTS state before posting the send work request.

The IB specifcation says that this error indicates an internal QP 
consistency
error. What are the possible reasons for this and is there any way I can
pin point the inconsistency ?

I would appreciate any hints to resolve this error.

Regards,
Ram
