I see the following in my logs:
2020-05-08 13:46:37,457 WARN - JGRP000015: the send buffer of socket MulticastSocket was set to 5.00MB, but the OS only allocated 212.99KB. This might lead to performance problems. Please set your max send buffer in the OS correctly (e.g. net.core.wmem_max on Linux)
I’m running HiveMQ in AWS EKS and would like to know if I should tune this parameter as I’ve thought multicast was not supported in AWS.
