well thats one of reported issues. I think this is erlang issue, but
probably it can be workaround by "building-in" some kind of heart-beats.
Probably Aleksey or Mickaël Rémond can write some more about that problem.

btw. when 2 or more nodes have network issues between them - it can lead to
very serious problems, including database inconsistencies (mnesia), presence
problems etc...
