Hello,
I'm interested in master fail over functionality. Your framework seems to
provide it, but I couldn't get it working (tried ApplicationServer example
and ClusterManager app).
I ran two instances (core type) on two different hosts. At start-up one
becomes Master the other acknowledges it. When I kill one instance the other
sees it but does NOT try to become a master (isMaster: false).

When the original master node is restarted it keeps sending a system
advertisement to the other node non-stop every 3 seconds (it did not do it
before crash):

On which the other node prints:

Is it expected behavior or am I missing something? Do I need to change
anything in the configuration to enable master fail over?
