Is esb2:38181 the instance you bring down or second instance on which
request need to be failed over? If it is second instance, then until it
is detected to be healthy, you will see blue screen as there is no
healthy instance to service your request. In such a case, I don't see
any logs for instance1 which is brought down by you.
I am not sure why you are not able to telnet. May be some system/network
configuration issue?
Thanks,
Kshitiz

When I tried to check my configuration with sample clusterjsp application, after stopping one instance that had served requests, the other one did not take them over. Instead, I got a violet screen showing problem with server.
