This is an OpenPGP/MIME signed message (RFC 4880 and 3156) ------enig2XELEWWATAANBQTANMPNP Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hello, I have two machines connected back-to-back via Infiniband with Mellanox Infinihost III adapters. One machine runs Linux (Fedora 19) and the other 9-STABLE. I sometimes get: ib1: timing out; 47 sends not completed ib1: timing out; 1 sends not completed ib1: timing out; 56 sends not completed or similar and TCP connections will be stuck after each timeout for a while. It is relatively easy to reproduce this behavior with NetPIPE. Any advice?
