Can you explain in more detail exactly what happened here?

It sounds like you have three hosts with colocated OSDs and monitors, triggered a net split, and then saw OSDs go down on a host you did not expect, but I'm not sure. That could easily happen depending on your monitor configuration and is not necessarily a bug.
