Your installation deployment is broken. You should look at root cause (check the logs). In your situation the local_config table is seen missing by ets module so something went very wrong before. It may be related to your custom local modules.
Check the log for previous errors.
My rabbitMQ service is crashing as soon as I start it. The service was running fine for last two years but suddenly, it stopped working. I looked at the log and saw this:

rabbitmqctl set_vm_memory_high_watermark 0.5
it gives following error:

Elixir v1.0.3 does not work with Erlang 17.5. You need to either update Elixir to v1.0.4 or downgrade Erlang to 17.4.
the error enotsup denotes an operation not supported on your platform. check if elixir is correctly compiled, the error occurs at the very beginning of the elixir startup.
I was about to install Sensu with Chef, but RabbitMQ does not seem to be working. The service of rabbitmq-server does not start, even though installation of erlang and RabbitMQ was successful.
The error of rabbitMQ says
Error: unable to connect to node rabbit#localhost: nodedown
and
rabbitmq service has already started
So I checked the process of rabbitmq with ps command.
ps aux |grep rabbitmq
for sure one process is running with rabbitmq user
/usr/lib64/erlang/erts-6.1/bin/epmd -daemon
I killed that process, and restarted the rabbitmq-server service. However failed to start rabbitmq-server and the same log was shown the same thing and the same thing happened.
I once removed the erlang and rabbitmq and reinstalled them, but the result was same.
The followings are the detail.

It looks like the port that RabbitMQ (5672 to be exact) is using is already taken. Or in your case it might be still taken. If you kill application that opened socket on some port, you are not giving it time to close this connection properly. System will eventualy notice this and free the resource, but it might take some time. So what you could do is wait a little, or change RabbitMQ configuration.
Hope this will help with some of your problems.
I have a debian box running tasks with celery and rabbitmq for about a year. Recently I noticed tasks were not being processed so I logged into the system and noticed that celery could not connect to rabbitmq. I restarted rabbitmq-server and even though celery was not complaining anymore it was not executing new tasks now. The odd thing was that rabbitmq was devouring cpu and memory resources like crazy. Restarting server would not solve the problem. After spending couple hours looking for solution online to no avail I decided to rebuild the server.
I rebuilt new server with Debian 7.5, rabbitmq 2.8.4, celery 3.1.13 (Cipater). For about an hour or so everything worked beautifully again until celery started complaining again that it can't connect to rabbitmq!
[2014-08-06 05:17:21,036: ERROR/MainProcess] consumer: Cannot connect to amqp://guest:**#127.0.0.1:5672//: [Errno 111] Connection refused.
Trying again in 6.00 seconds...
I restarted rabbitmq service rabbitmq-server start and same issue gain:
rabbitmq started again swelling up constantly pounding on cpu and slowly taking over all ram and swap:

UPDATE:
Seems like problem was solved when installed newest version of rabbitmq (3.3.4-1) from rabbitmq.com repository. Originally I had one installed (2.8.4) from Debian repositories. So far rabbitmq-server is working smoothly. I will update this post if issue comes back.
UPDATE:
Unfortunately after about 24 hours the issue reappeared where rabbitmq shut down and restarting the process would make it consume resources until it shuts down again within minutes.
Finally I found the solution. These posts helped to figure this out.
RabbitMQ on EC2 Consuming Tons of CPU
and
https://serverfault.com/questions/337982/how-do-i-restart-rabbitmq-after-switching-machines
What happened was rabbitmq was holding on to all the results that were never freed to the point it became overloaded. I cleared all the stale data in /var/lib/rabbitmq/mnesia/rabbit/, restarted rabbit and it works fine now.
My solution was to disable storing results alltogether with CELERY_IGNORE_RESULT = True in the Celery config file to assure this does not happen again.
You can also reset the queue:
Warning: This clears all data and configuration! Use with caution.
sudo service rabbitmq-server start
sudo rabbitmqctl stop_app
sudo rabbitmqctl reset
sudo rabbitmqctl start_app
You might need to run these command right after rebooting if your system is not responding.
You are running out the memory resources because of celery, I got a similar issue and it was a problem with the queues used by celery backend result.
You can check how many queues there are using rabbitmqctl list_queues command, take attention if that number grows forever. In that case check out your celery use.
About celery, if you are not getting the results as asycronous events dont configure a backend for store those unused results.
I experienced a similar issue and it turned out to be due to some rogue RabbitMQ client applications.
The issue seems to have been that due to some un-handled error, the rogue application was continuously trying to make a connection to the RabbitMQ broker.
Once the client applications were restarted, everything went back to normal (since the application stopped malfunctioning and there for stopped trying to make a connection to RabbitMQ in an endless loop)
Another possible cause: The management-plugin.
I'm running RabbitMQ 3.8.1 with enabled management-plugin.
On a 10-core server I had up to 1000% CPU-usage with 3 idle consumers and not a single message being sent, and one queue.
When I disabled the management-plugin by executing rabbitmq-plugins disable rabbitmq_management the usage dropped to 0% with occasional spikes of 200%.
