Load Balance/ Failover on Application server
We are facing a major issue at appserver failover level. We have 4 Applcation servers (A, B,C,D)defined in config.prop file with port on webserver.
If we manually bring down app server A, the traffic routes to other server (B C and D). but if for some reason there is an issue with UNIX box A and we cannot telnet or ssh to the box then the user doesn't get routed to another server (B C and D). So configuration.properties still thinks its an active server. e.g This morning I noticed that Server A had the follwing issue.
