Hello,
I am on Dropwizard 1.0.0 , Java 1.8 and have a few services running in
there. Since the services are not in production yet, hence there are
periods when no one is accessing those services.
What i notice is that Jetty shuts down automatically and gracefully after
some period of inactivity. The inactivity period is not consistent and it
goes down at random times. Here is an excerpt from the logs
DEBUG [12:34:34.693] [dw-21] o.e.j.u.t.QueuedThreadPool - ran EPC
Prod/org.eclipse.jetty.io.ManagedSelector$SelectorProducer@432959e3

DEBUG [12:57:24.221] [Thread-13] o.e.j.u.c.AbstractLifeCycle - STOPPED
i.d.j.MutableServletContextHandler@5bfa8cc5{/,null,UNAVAILABLE}
This time it went down after 23 minutes of inactivity, there are times it
goes doen after 6 minutes, 12 minutes etc.
Any clues? Should i have a dummy service which simply pings every minute to
keep it alive. I have used 0.9.2 for a 6 months and never faced this issue
earlier.
Any pointers are appreciated.
Thanks
Vaibhav
