Hi Tom,
Thank you very much for your response.
Yes, my Rackspace servers have multiple network interfaces, one of which is LAN interface, we are using those local IPs in the hazelcast config file:
<tcp-ip enabled="true">
<member>X.Y..3.1:5701</member>
<member>X.Y.3.2:5701</member>
</tcp-ip>
Same for the DB, we are using the local LAN interface IP. We have also tried the same by stopping iptables on the two chat servers.
When this problem occurs, I did a netstat -anp | grep 5701, it shows a connection between X.Y.3,1 & X.Y.3.2
Also this problem is intermittent and only happens for one of the servers Chat02, meaning sometime the clustering page shows both the servers, some time it does not. The other server Chat01 can show both the servers Chat01 & Chat02.
Any insight would help.
Best Regards,
Shil
