I've logged this issue: https://github.com/eclipse/kura/issues/684

I wanted to put this to the forum anyway, in case someone can correct me if i am mistaken or direct me to a way of stopping the watchdog before exiting?

thanks, paul.

Turns out, stopping the watchdog bundle, eg "stop 58" prior to calling "exit" resolves the issue. However this raises a larger issue of there not being an easy way to cleanly shut down kura (easily). I would expect "exit" to cleanly exit, whereby all components are "deactivated" or "stopped" before the process exits. Does this feature exist? I believe it should...

Hello,
we just realized that there was a nasty bug in watchdog service: when the watchdog is disabled the thread is terminated before having disabled the watchdog. I will fix it in the next release.

Concerning osgi exit command it is working like a kill and do not stop the services cleanly.You should use osgi>shutdown or call /etc/init.d/kura stop. In this case the watchdog will be disabled correctly.

Regards

"osgi> shutdown" is doing some funny things - like deactivating and then activating Components.

Hi Paul,

Could you use "/etc/init.d/kura stop" for terminating the process? This essentially stops bundle 0 (the system bundle) then allows the start-stop-daemon to shutdown the process based on the PID file.

I would have to check on what is happening with "shutdown", it is not something I regularly use in Kura.

Thanks,
--Dave

Just a follow up - we routinely use:

osgi> ss watch
id      State       Bundle
77      ACTIVE      org.eclipse.kura.linux.watchdog_1.0.201
osgi> stop 77
osgi> exit

this process avoids kura restarting.
