This is a follow up to
ERL-770 but seems like a separate issue. We are using Erlang 21.1.3 patched with the ERL-770 one-liner. As previously mentioned, we are running RabbitMQ 3.7.8 on two 3 node clusters on Ubuntu 16.04 on XenServer hosts. All Erlang distribution links are running on a local gigabit network.
