[rabbitmq-discuss] RabbitMq not honouring high_watermark setting?

Wed Jul 13 12:42:45 BST 2011

Hi all,

I'm trying to tweak Rabbit 2.5.1 on a server running Windows Server
2008 x64 with 8gb ram.

My rabbitmq.config file looks like this:

[
  {rabbit, [
     {ssl_listeners, [5671]},
     {ssl_options, [{cacertfile,"C:/CAConfig/trustisroot.cer"},
                    {certfile,"C:/CAConfig/publicCertificate.pem"},
                    {keyfile,"C:/CAConfig/private.pem"},
                    {verify,verify_peer},
                    {fail_if_no_peer_cert,false}]},
     {vm_memory_high_watermark, 0.4}
   ]}
].

However Rabbit starts up with the standard 819mb memory limit.

Any ideas where I'm going wrong?

Thanks in advance,
