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.
