Hi Knut,

Let me see if I understood correctly. The problem is not continuous for the
same machine, but only from time to time? If not, check your installation
because, as far as I know, node-to-node communication uses RPC which, in
this case, needs to be set to accept communication without entering any
user/password (key-pair authentication and the processes to belong to the
user for which the key was created). Otherwise, if the problem appears and
disappears for a machine, there are few things which you can check:
1. If OTP (application/monitor/gen_server), check what your monitor is
reporting and see if you can match any crash/attempt to restart a generic
server.
2. Check if your listener is not busy.
3. In case of sending to a spawned thread, if the thread is up.
...and so on. You can notice that the more info you give us, the better for
us to understand your problem. Parts of the log would be very helpful (just
don't forget to replace the sensitive data with generic ones - e.g.,
mydomain.com with example.com).

Cheers,
CGS
