All,
I have a clustered RabbitMQ service running 3.1.5. Both servers are Ubuntu
12.04 VMs running on ESX Vmware. Both have 16 CPUs and 32 GBs of RAM and
100 GBs of storage.
I have 10 Queues and multiple clients connecting around 1,000. My CPU is
running at 300 % on the beam.swp process. Also my RabbitMq management
console is reporting 5800 erlang processes. Any ideas what I might be
missing? I have attached my rabbitmqctl report output below.
Reporting server status on {{2014,6,6},{22,48,23}}
