Comment 8 for bug 1279594

Only in HA mode we deploy /etc/security/limits.conf file with higher than standard values (during corosync_setup stage). So on simple CentOS env we also have 1024 files limit, I've just checked on a live env. I don't have a live HA ubuntu env to check, but it also should have 102400 open files limit since we deploy /etc/security/limits.conf file there as well.

In my opinion, the best way to solve this is to include "/etc/default/rabbitmq-server" file in our rabbitmq packages which will have reasonable defaults. This file is being sourced by the current init scripts already, so we just need to add it.
