Why does my cluster not work property after installing a single user (non-root) cluster?

If you install and start a Platform EGO cluster as a root user, and then uninstall it, certain temp files may remain in a UNIX /tmp directory that could cause startup problems for future installations. Prior to reinstalling Platform EGO, you must shutdown the cluster and remove /tmp/secegocc_* and /tmp/.pem.$clustername. This is particularly important if you are reinstalling a single user (non-root) cluster.
