-------------------------------------

Hi Alex,

unfortunately I cannot give you the heap dump of the OOM since it may contain company related
data, that should not be public.

Can you tell me any tools and manuals to investigate the memory problem myself ?

Thanks in advance.

> - install ruby amqp bunny
> sudo gem install bunny
> - download hello bunny example
> wget http://pastebin.com/raw.php?i=f6MesMCZ -O hello_bunny.rb
> while true; do ruby hello_bunny.rb ; done
