[jira] Reopened: (KARAF-327) Graceful shutdown of Windows service,
revisited
[ https://issues.apache.org/jira/browse/KARAF-327?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Achim Nierbeck reopened KARAF-327:
----------------------------------
I reopen it as I guess this didn't do the trick yet :(
could you please provide a Sample with camel so I can test this?
You are right, the action takes place in the class org.apache.karaf.shell.wrapper.Main.
My presumption was that I tell the framework to shut down and wait for it, now I would
have expected that the camel route can be safely be shut down.
The actual 1.5 seconds should be the waiting time added to the wrapper during looping.

> Issue Type: Bug
> Components: wrapper

> I'm trying to make my Karaf service more resilient to shutdown. In particular I want my Camel routes to shutdown gracefully. I started this discussion a few months ago, see http://www.mail-archive.com/user@karaf.apache.org/msg00084.html.
> Guillaume created the JIRA ticket KARAF-176 which is also resolved. I haven't had time to test this until now.
> It seems to me that the problem persists. I'm now using Karaf 2.1.2 and Camel 2.5.0. When I run Karaf from the command line and terminates Karaf by pressing <ctrl-D>, Camel will gracefully shutdown. It looks something like this:

> Nothing more is logged since the process is killed. I know that there is never a guarantee that Karaf will shutdown gracefully since the process might just die (e g out of power). But it would be nice if the control panel could be used for stopping the service since thats what most operations engineers do. There is always the option to log in to Karaf via SSH and issue the shutdown command before stopping the service but then it becomes too complicated for most people.
