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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
