Resolving an addressing conflict requires access to the privileged shell of the Gateway. Please execute the following procedure to manually resolve addressing conflicts.
1. Determine the jGroups cluster master by running this command on a database node.
# mysql ssg -e "select cluster_info.address from cluster_master, cluster_info where cluster_info.nodeid = cluster_master.nodeid;"
NOTE: The jGroups cluster master is not the same as the MySQL replication master.
2. Restart the SSG node serving as the jGroups cluster master.
NOTE: Do not continue until the previous step is complete.
3. Restart the impacted node unable to join the jGroups cluster.
Both nodes should successfully join the jGroups cluster without issues. If the issue persists, please contact Layer 7 Technologies Technical Support.
The jGroups implementation exists solely to facilitate multicast replay protection. If replay-related assertions or functionality are not in use on the Gateway and you are seeing this error consistently, you may choose to disable multicast replay protection via the cluster-wide property "cluster.replayProtection.multicast.enabled". To disable replay protection, set this cluster-wide property to "false."
