>There are also IPoIB CM IP multicast problems, see bug 418. Bug 418 looks different than bug 400.
>From the bug report, it sounds like this error is limited to IPoIB CM mode. Is this correct? >If you try to multicast packets > 2KB, you see: I'm not sure if your hardware supports a max MTU of 2K, but in general I thought multicast would work up to 4K. Can you verify that the device MTU is higher than the packet size? >ib0: failed send event (status=1, wrid=35 vend_err 69) It looks like this indicates a local length error on the send. >ib_mthca 0000:08:00.0: modify QP 3->3 returned status 10. >ib0: failed to modify QP, ret = -22 >ib0: couldn't attach QP to multicast group This looks like a RTS -> RTS QP transition to set the QKey. I'm not sure what the ib_mthca status code of 10 is, but that may give us a hint at the problem. This error and the attach QP to multicast group error may be related. - Sean _______________________________________________ general mailing list general@lists.openfabrics.org http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
