Marcus Christie commented on AIRAVATA-2373:
-------------------------------------------
Also, can we add a Zabbix alert for this? And can we add it as part of the
Ansible scripts?
> Increase open file descriptor limits for RabbitMQ server
> --------------------------------------------------------
>
> Key: AIRAVATA-2373
> URL: https://issues.apache.org/jira/browse/AIRAVATA-2373
> Project: Airavata
> Issue Type: Bug
> Components: GFac
> Reporter: Marcus Christie
> Assignee: Marcus Christie
>
> Ran into a problem on gw56 where GFac wasn't able to make a connection to
> RabbitMQ because RabbitMQ hit the open file descriptor limit of 1024.
> Using
> http://clouddoc.stratus.com/1.5.1.0/en-us/Content/Help/P03_Support/C02_InstallGuide/C05_OpenStackInstall/T_RabbitMQLimits.htm
> as a guide I created a file called /etc/default/rabbitmq-server on gw56 with
> the following contents:
> {noformat}
> ulimit -n 65536
> {noformat}
> Then I restarted RabbitMQ. I verified the new limit:
> {noformat}
> [root@gw56 ~]# grep -e Limit -e files /proc/$(cat
> /var/run/rabbitmq/pid)/limits
> Limit Soft Limit Hard Limit Units
> Max open files 65536 65536 files
> {noformat}
> Then I restarted GFac and it was able to connect to the process_launch queue
> again.
> It would be good to research if this is the best way to increase open file
> limits and then get it into the Ansible scripts.
