</div>The 0.4 is a scaling of the RAM that Rabbit detects in your machine.<br>
Furthermore, as the documentation says, it is *not* a limit for how much<br>
RAM rabbit will use. As I pointed out in my other email, Erlang is a<br>
GC'd language. The 0.4 simply says that channel.flow will be invoked<br>
once 0.4 of available RAM has been used by Rabbit. This does not<br>
preclude Rabbit from using more than 0.4 - the GC events may cause up to<br>
twice this to be used. In addition, it is beneficial to allow your OS to<br>
have some RAM available for disk caches, thus allowing it to be able to<br>
satisfy reads without having to go to disk.<br>

</div>The first line should be placed in rabbitmq.config. The second line is<br>
valid for rabbitmq.conf. Note they are two very different files.<br>
rabbitmq.config is an Erlang term file. rabbitmq.conf is sourced by the<br>
various shell scripts thus is a location to configure shell variables.<br></blockquote><div><br></div><div>Ohhh thanks... so we have two different config files.. well thanks I really thought that this configurations live inside the same file. Know rabbit run ok.</div>
