1. Malware Analysis Appliance system status on management UI shows red with health error on "RabbitMQ server is not runing"

2. /var/log/syslog shows health stats error exception page similar to below example:

'---------------------------------------- START OF EXCEPTION----------------------------------------'
Sep 21 10:43:17 (none) health[3036]: ''
Sep 21 10:43:17 (none) health[3036]: "  LOG MSG         : 'Failed to fetch rabbitmq status'"
Sep 21 10:43:17 (none) health[3036]: '  EXCEPTION CLASS :exceptions.AttributeError'
Sep 21 10:43:17 (none) health[3036]: "  EXCEPTION MSG   :''NoneType' object has no attribute 'split''"

<truncated for brevity>

3. Rabbitmq service shows error status similar to below example:

  [email protected](none):~# rabbitmqctl status
  Status of node '[email protected]' ...
  Error: unable to connect to node '[email protected]': nodedown

4. Rebooted and after coming back up, cannot login to the management UI.


The rabbitmq service isn't starting and in most cases the system is having a corrupted mnesia database in /var/lib/rabbitmq/mnesia directory


Deleting the rabbitmq 'mnesia' data store should resolve this issue (mnesia data store will repopulate as needed)

* Log in via SSH as 'g2' (or log onto the console)
* Run below and provide the 'g2' password when needed

[email protected](none):~$sudo supervisorctl stop all <-- this can take a few minutes
[email protected](none):~$sudo /etc/init.d/rabbitmq-server stop
[email protected](none):~$sudo rm -rf /var/lib/rabbitmq/mnesia/*

Then reboot the box; rabbitmq should start properly and the dependent services should as well. Upon boot up, re-check the rabbitmq service using "sudo rabbitmqctl status" or "/etc/init.d/rabbitmq-server status"

1. Make sure normal output as below shown:
[email protected](none):~# sudo rabbitmqctl status
  Status of node '[email protected]' ...
<truncated for brevity>

2. Make sure the process is running similar to below output: (There should be 5 processes running as the user rabbitmq.)
