Comment 12 for bug 1771340

@ahasenack, of course I could double check. I've done so a few minutes ago and you are right. After trying to reload with a corrupted config file the reload failed but the service is still up and running.

Please see the following output for confirmation:

Sorry, that I didn't get it in the first try.

The update looks fine for my, too.
