> We had an issue today (Jul 25th, 2017) of Jenkins running out of file descriptors.
> Things already reached the point where Jenkins was barely functioning so to get things back to working order I've:
> * Manually added a line in '{{/etc/security/limits.conf}}' to set 'nofiles' to 16384 for the 'jenkins' user (Previously it was just not configured and seems to have defaulted to 4096).
> * Restarted the 'jenkins' service.
> We now need to:
> * Place this configuration in Puppet/Ansible.
> * Add monitoring so we'll know in advance the next time Jenkins goes near to the nofiles limit.
