Not sure, but re. your next question;

~# sysctl fs.file-max
fs.file-max = 6513989
~# cat /proc/sys/fs/file-max
~# cat /proc/sys/fs/file-nr
416 0 6513989
So I assume we don't need to change /etc/sysctl.conf since the maximum
limit is much higher than the 102400 we're trying to allocate for RabbitMQ.

We installed Erlang using the esl-erlang package from erlang-solutions.
How can I check if epoll support is enabled? I'm not very Erlang
literate I'm afraid.
