Helo,
Second time i experience strange situation with ejabberd running on multiple nodes (3). I have describe that on bugtraq few months ago.
If we have 3 nodes (ejd) that work as cluster and are interconnected, and we break connection to - let say - first node for some period of time, and fix that connection again, nodes will not reconnect. That situation lead to very very unpredictable behaviours - because - f.e.load balancer "see" that all nodes are working correctly, and it directs connections to that nodes, that lead to strange situations like, wrong s2s negotiations and many others.
So my question is: is that bug in ejabberd or in erlang itself?
If in erlang - is there any way to "force" nodes to periodically check if offline nodes (that look like they are offline - but they are not) come back to life?

I am not sure I understand correctly your scenario. Do you mean that you
cut the connection between the mnesia nodes but the client connections
are still going normally to all nodes ?
