Subject Re: CleanupHandler not always running
Date Sun, 27 Dec 2015 15:41:39 GMT
Philippe,

I think you are on to something.  We use graceful-stops and we reset the
counters during a subsequent start.  It looks like the counters sometimes
come out of the graceful-stop / start with an elevated number which
supports your theory.  Do you recommend using a LogHandler instead of a
CleanupHandler?

Thanks!

Paul
