ulimit default

[opennomad]

I was runnning into an issue where new connections were being refused and tracked it back to the ulimit -n 1024 in the rabbitmq-start script.

Is there a reason for setting that? Perhaps making it based on an ENV value with default if it's not provided would be a good alternative?

I tried the following and it seems to work like a charm in my test case:

#!/bin/bash

if [[ "${RABBIT_ULIMIT}" ]]; then
    ulimit -n "${RABBIT_ULIMIT}"
else
    ulimit -n 1024
fi
chown -R rabbitmq:rabbitmq /data
exec rabbitmq-server $@

Then I just add -e "RABBIT_ULIMIT=unlimited" or some value instead of unlimited and I am able to handle the number of connections I need.
