it's a really strange problem!
Can you please make another test?
after having stopped nut (mge-shut, upsd and upsmon), simply launch
"mge-shut -DDDDD -a yourups", let it run for 1 or 2 mn and send me
back the output.
I'll try on my side a sol8 install to see if there is something on that front.
About your leaders, simply tell them that you won't get better support
than MGE's on Unix ;-)

you have also the option of a network management card, with our new
Network Shutdown Module (still beta):
