I'm experimenting with Tomcat 9.0.8 enabling Cluster support. I've uncommented the line for it within the server.xml. I have 4 separate servers on different hosts, all with the same config, except unique jvmRoute values. Upon startup, it appears that server1 and server4 pair up and server2 and server3 pair up, every time! I'm using the default udp multicast, again, just uncommenting the single cluster line in server.xml. I'm expecting that all 4 would see each other and I would have a single cluster of 4, not 2 clusters of 2. I confirmed each server can see each other over port 4000. Any help is appreciated.
Regards, Tim
