That caused the following error in our Logfile, preventing PRPC to start.
[11/4/16 9:55:12:766 CET] 000000a9 DefaultAddres E com.hazelcast.instance.DefaultAddressPicker [LOCAL] [304a66e962c6507bc03eefdff9611be1] [3.4.1] Port  is already in use and auto-increment is disabled. Hazelcast cannot start.
java.net.BindException: The socket name is already in use.
That's wat I assumed also, bout, how to prevent that or let Hazelcast use another port? I can specify a broader range that 5701-5703, but then I need to know first if that will help. Specifying nothing is possible, but, is that the right thing to do?
In our pega cloud environment we are not specifying the port and allowing hazelcast to use available ports.If you want to use a range then please extend the range. Also, make sure these range ports are open and free (not occupied by any other process).
