Increasing max-open files for beanstalkd

February 28th, 2015 • By Cory Virok

Quick tip: If you are running out of file descriptors in your Beanstalkd process, use /etc/default/beanstalkd to set the ulimit before the init script starts the process.


# file: /etc/default/beanstalkd
BEANSTALKD_EXTRA="-b /var/lib/beanstalkd -f 1"

# Should match your /etc/security/limits.conf settings
ulimit -n 100000

Lots of resources online tell you to update your /etc/security/limits.conf and /etc/pam.d/common-session* settings to increase your maximum number of available file descriptors. However, the default beanstalkd installation on Ubuntu 12.04+ uses an init script that starts the daemon process using start-stop-daemon which does not use your system settings when setting the processes ulimits. Just add this line to your defaults and you're good to go!
