Thanks for the tip Juri - I hadn't thought of that tack.  The 2nd instance of mon keeps failing to load with a port in use error as I can't seem to convince mon to take the "-p <portnum>" argument, so I'm currently trying the mon-in-control method now.  I'll probably try the service group enable/disable method anyway, just to get a feel for it.

thanks,

Paul.
