[erlang-questions] R12 connection problems from Java

Hi!

I wonder if anyone has seen this problem before: from Java we start an
erlang runtime and sit in a loop, calling ping, until it responds. I
have registered a NodeStatus instance that receives messages related
to remote nodes. It correctly prints a IOException for the period
until the erlang node responds.

The problem is that sometimes, for some users, these messages are
followed by OtpAuthExceptions. Restarting usually helps, so it's not a
persistent problem (like having the wrong cookie), but it may happen
again later. This has been seen only with R12B (I think R12B-4), R11
doesn't act the same way.

I couldn't debug this situation because it never happened to me.
Anyone has any hint about what happens?

best regards,
Vlad
