Hi Imesh, Thanks for the reply. I set the configuration as *topology-event-listener: false; * Then I got below exception while starting the load balancer.
Hi Nirmal, In WOS2 ELB configuration file, there is a configuration as *group_mgt_port 4500; *[1] How can I map this configuration in the Stratos load balancer?
