Hi Jean Paul. On Ubuntu / Debian we now start RabbitMQ with 
start-stop-daemon, which quite explicitly does *not* start a new PAM 
session, so the second change you made did does not take effect.

http://superuser.com/questions/454465/make-ulimits-work-with-start-stop-daemon

discusses this issue (in non-RabbitMQ-specific terms).

The best thing you can do is add a line to /etc/security/limits.conf for 
*root* - the RabbitMQ service will then inherit this.

Cheers, Simon
