I can't see the problem, it's just for testing purpose, while setting 
things up. Once done NUT must be restarted, if that schema is used. Need 
only to be mentioned in the man page.
Alarm messages can't get lost on TCP (unless explicitly dropped).

Ok, I didn't noticed it at first: the NMC keeps resetting all the 
subscription connections when using other clients along with NUT. 
However it started working like this after the netxml-ups upgrade. Had 
to stop NUT. I never experienced such issue before.
Ok, found... the netxml-ups driver keeps asking the get_object page 
really often.

Network traffic sniffing (tcpdump in particular).
