Foglight HA logs have frequent warnings for packages being discarded due to a version mismatch (4374787)

When JGroups is configured to use TCP instead of UDP, complete the following steps in all the HA nodes to use a different port than the one used by the conflicting application:

1. Make a backup of the JGroups configuration file [FMS_HOME]/config/jgroups-config.xml.
2. Apply the following changes:
   • Under the TCP element, set the port in the bind_addr attribute to the desired one.
   • Under the TPCPPING element, set the port for each host in the initial_hosts attribute to the desired one.
3. Save changes and restart the HA nodes.
