moxi err msg improvement

That's very strange -- so, beyond the admittedly uninformative error message (will fix that), on a root cause level nothing's changed in the moxi or ns_server components in 1.6.5 that should have broken this. That error message indicates that moxi got an empty config message from ns_server. I'm guessing there might have been a slow startup in ns_server, or something like that.

Subject: Moxi version compatibility

Steve, I ran into a weird issue today where build 7 of the 1.6.5 Moxi server would not work with build 1 of the 1.6.5 Membase Server. The error message was none too helpful:
2011-01-10 19:38:45: (agent_config.c.1174) ERROR: invalid config from REST server

Can you add some better error checking and error reporting to let the user know that they need to have a specific version (and what that version is) of both sides in order for the Moxi->server connection to work?

Thanks

Perry
