Sometimes logstation does not start tailing files

[Kkevsterrr]

Original problem: Sometimes when logstation starts, it just does not tail any files.

I cannot tell the difference between a launch that will fail or succeed. Once the next run does not work, I will post the full traceback.

==================================================
Original issue I opened/errors reported: (though all of these appear in both the successful and unsuccessful runs)

I'm seeing these two errors often before logstation stops working, so I figured I'd open an issue just to ask if they are a problem, or something else.

06:44:41.194 [main] INFO o.e.j.w.StandardDescriptorProcessor - NO JSP Support for /, did not find org.apache.jasper.servlet.JspServlet

06:44:41.407 [main] ERROR net.liftweb.util.Props - Failed to find a properties file (but properties were accessed). Searched: /props/root.ubuntu.props, /props/root.props, /props/ubuntu.props, /props/default.props, /root.ubuntu.props, /root.props, /ubuntu.props, /default.props

On shutdown (when nothing shows up in logstation):
[INFO] [10/15/2018 06:49:44.371] [LogStation-akka.actor.default-dispatcher-7] [akka://LogStation/user/LogStationServiceActor] Message [akka.actor.Terminated] from Actor[akka://LogStation/user/LogStationServiceActor/LogTailerActor-:worker0:#-649459367] to Actor[akka://LogStation/user/LogStationServiceActor#1772589764] was not delivered. [1] dead letters encountered. This logging can be turned off or adjusted with configuration settings 'akka.log-dead-letters' and 'akka.log-dead-letters-during-shutdown'.

Update: all three of those lines appear during a functional run of logstation, so I'm at a loss :/ Will update the issue with the problem

Hmm I wonder if there's a permission problem? Maybe logstation was not allowed to read the files?

Going to close this issue for now. Please feel free to comment with any new info and we can reopen it.
