Symptoms

A TCP listener is configured to listen on a virtual ip (VIP) that is configured for a failover group. After disabling the listener via the admin console and then subsequently deploying the change, the console hangs for 1 or 2 minutes and then gives an error that says the deployment on one node (<HOSTNAME1>) is successful and the deployment on the other node (<HOSTNAME2> ) failed due to the node being unreachable.

The issue is reproducible even without using the admin console for deployment of the config change.  It can be reproduced using the following sequence:

  1. Increase the number of acceptor threads for a listener to a higher value (e.g 96).
  2. Start the instance with the listener enabled.
  3. Manually edit server.xml to disable the listener  (e.g:  <enabled>false</enabled> )
  4. Run /bin/reconfig on the instance that doesn't have VIP running
