Chris, all,

We are also seeing similar messages primarily on our servers, but from lnet_handle_local_failure() instead. I don't find any issues with the local o2ib interfere, yet, but there _may_ be a correlation with a client hang. Could this also be caused on a server by remote network problems or a client dropping out, in spite of the "local" name?

Thanks,
Nathan

The message means that the health value of a remote peer interface has been decremented, and as a result, the interface has been put into recovery mode. This mechanism is part of the LNet health feature.

Health values are decremented when a PUT or GET fails. Usually there are other messages in the log that can tell you more about the specific failure. Depending on your network type you should probably see messages from socklnd or o2iblnd. Network congestion could certainly lead to message timeouts, which would in turn result in interfaces being placed into recovery mode.
