Summary: 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)
