So you ran out of descriptors and inotify is getting you down...

We are tweaking so default system values on all hosts to skirt the following issue:

https://github.com/guard/listen/wiki/Increasing-the-amount-of-inotify-watchers

As discussed here: https://runnable.atlassian.net/browse/SAN-3510

The values are -

• limits.conf

root soft nofile 1048576 root hard nofile 1048576 * soft nofile 1048576 * hard nofile 1048576 root soft nproc 1048576 root hard nproc 1048576 * soft nproc 1048576 * hard nproc 1048576

• sysctl.conf

fs.file-max = 100000000 fs.inotify.max_user_watches = 524288 fs.inotify.max_queued_events = 65536 fs.inotify.max_user_instances = 8192

If you change the limits.conf, you will need to reboot. Changing kernel parameters in sysctl.conf can be applied with a sudo sysctl -p.
