Looks like with the recent additions to Kibana we might hit the default limit on certain OSs. I think we should do the same thing that ES uses for file descriptors:
- add a bootstrap check (could be a warning for now)
- add a note in the docs on the error message and what to do to fix this:
changingfs.inotify.max_user_watches=8192in/etc/sysctl.confto a higher number.
We can also investigate the increase in file watches and see if we can limit that somehow.
