<P class=MsoNormal><SPAN lang=EN-US>I am hitting the following QP error </SPAN></P>

<P class=MsoNormal><SPAN lang=EN-US>My application is a 4 nodes distributed client-server program that leverages the RDS features (i.e. sendmsg and recvmsg) only, i.e. without RDMA. I checked all cables connections and they are fine. All IB (Mellanox) drivers were loaded.</SPAN></P>
<P class=MsoNormal><SPAN lang=EN-US>Any ideas why RDS returns this error?</SPAN></P>
