    Description

      Summary

      Changes to a node in a Crowd Data Center cluster can cause a duplicate entry to be seen in the clustering admin page <crowd-base-url>crowd/plugins/servlet/cluster-monitoring. This is particularly confusing because it appears as if 3 nodes were in the cluster when really there are only 2. (see screenshot)

      Environment

      • Crowd
      • Data Center

      Steps to Reproduce

      1. Create node 1 in a Crowd Data center environment with DC License via these steps https://confluence.atlassian.com/crowd/installing-crowd-data-center-935369773.html
      2. Configure and bring up node 2
      3. Visit the cluster page and note that two nodes appear in the cluster: <crowd-base-url>crowd/plugins/servlet/cluster-monitoring
      4. Visit the node 1 install directory <crowd-install>/apache-tomcat/bin and edit setenv.sh file
      5. Note the following values JAVA_OPTS="-Xms128m -Xmx512m. Edit the file and change* -Xms128m* to -Xms512m
      6. Save the file and restart Crowd on Node 1
      7. When the node is online, visit the clustering page: <crowd-base-url>crowd/plugins/servlet/cluster-monitoring

      Expected Results

      You will see both nodes in the cluster

      Actual Results

      A duplicate entry appears for Node 1 and it appears as if three nodes are in the cluster instead of two.

      Workaround

      The duplicate entry will eventually disappear from the clustering page.
