Re: down consoles fail to reconnect automatically

What you’re doing sounds all correct, as are your expectations (it should attempt to bring up any downed consoles).  My simple test setup shows that it works for me, but with lots of consoles, there could be a bug or some side-effect that happens with more.  Or possibly some config settings that aren’t playing well together.  Do you have any “interesting” messages in the conserver log file that appear when you run the command?
