[rabbitmq-discuss] Rabbit Node Won't Boot No Matter What I Do (schema_integrity_check_failed)

Thank you, Tim and Matthias.

Tim: Yes, I'm aware that many of these things can use rabbitmqctl instead
of HTTP API.  I had started switching things to HTTP API (so, in theory, if
I ever need to put my own GUI on these commands, I'll know the calls)-- but
didn't get through it all yet.  In hindsight, maybe I should stick with
rabbitmqctl for now so I can more easily see what is going on.  Thanks for
making me think about it.

Regarding the startup of servers, that's a good point and something I had
thought of.  While troubleshooting, I inserted a "sleep 2" after the rabbit
startups to give them a couple of seconds to sleep.  I don't think I can
use "rabbitmqctl wait <pid_file>" because when I start the servers in
detached mode it specifically says: "Warning: PID file not written;
-detached was passed."  I tried "rabbitmqctl -n rabbita wait", but get back
an error saying it is an invalid command.  I guess I will experiment with
"sleep" again, but use a value greater than 2 seconds.

Matthias: After deleting the mnesia database I tried multiple times to get
the node up.  Maybe there was a different error the first time, but I noted
the error from subsequent times.  I'll try from scratch again and see what
happens.

Thanks again-- I really appreciate the pointers.

-Chris
