IssueThe rabbitmq-server service is in a failed state on the Security Analytics server.
The following messages are seen when attempting to stop and start the service:
[root@SA-Server ~]# service rabbitmq-server status
su: /bin/sh: Too many open files in system
[root@SA-Server ~]# service rabbitmq-server stop
Stopping rabbitmq-server: RabbitMQ is not running
rabbitmq-server.
[root@SA-Server ~]# service rabbitmq-server start
Starting rabbitmq-server: FAILED - check /var/log/rabbitmq/startup_
{log, _err}

 
CauseThe issue occurs because the underlying OS has not been configured to allow a high enough number of open files.
Resolution

In order to resolve the issue, perform the steps below to increase the number of open files handles and then start rabbitmq-server service.


  1. Check the current value before making changes.
    [root@SA-Server ~]# sysctl fs.file-max

  2. Set the value to survive a reboot.
    [root@SA-Server ~]# echo "fs.file-max = 30000" >> /etc/sysctl.conf

  3. Set the value in the live OS environment.
    [root@SA-Server ~]# sysctl -w fs.file-max=30000 
    [root@SA-Server ~]# sysctl -p

  4. Verify that the change has taken effect in the live OS environment.
    [root@SA-Server ~]# sysctl fs.file-max
