Re: [Resin-interest] Resin-4.0.5 Watchdog on Shutdown

[Rob Lockstone]

I submitted a bug on this new behavior when running Resin 4.x on Windows 
.

The problem is that when you issue a "stop" command to the resin service either 
via the sc (service controller) command, e.g. "sc \\serverName stop resin" or 
via "net stop resin", you can't then issue a "start" command to start up resin 
because Windows still thinks the service is running. We use this process for 
doing deployments or just general restarts from a central server.

I haven't tested this scenario, but another problem with this new behavior 
might be that if the watchdog doesn't know that a resin stop was specifically 
requested via the service controller, it might try to restart resin and that 
would be bad.

That's correct: you can just leave the watchdog running and issue a
start. Let us know if you run into the issue with port conflicts again.
It should only be a configuration issue.

To shutdown the watchdog, use "shutdown". "start/stop" only starts and 
stops the Resin instance.

Re: [Resin-interest] Resin-4.0.5 Watchdog on Shutdown

[Rick Mann]

Ah! Thanks. So, does that mean it's safe to leave the watchdog running, and 
just issue a "start" again? I seem to recall Resin getting mad that someone 
already had the port when I did that.

Re: [Resin-interest] Resin-4.0.5 Watchdog on Shutdown

[Emil Ong]

Hi Aaron,

This is the correct behavior. In 4.0.x, we changed the watchdog to be a
long-lived process.  If you'd like to shut it down, along with all
running resin instances, use the "shutdown" command.  We're in the
process of updating the documentation this week to reflect the change.

Thanks,
Emil
