We configured a horizontal cluster.
We configured two units, AP1 and AP2.

When AP1's OS suddenly shuts down, the IEE is unable to log in.
We think this is the wrong behavior for a cluster configuration.
What do you think?

We configured it by looking at the following F1 document.
  /ifsdoc/f1doc/foundation1/020_installation/020_installing_fresh_system/040_installing_ifs_applications/030_deploy_middle_tier/hidden_itd/200_configure_cluster_nodes.htm

When AP2's OS suddenly shuts down, I can login to IEE without any problem.
