I trust you ;-)

thanks for your directions, that did it.

a few more questions:
- does this happens with *all* the US units?
- is there anything special with these setups (like the UPS bundled in
a bigger packager, with possible EMI...)?
- can you try adding "notification = 1" (this will disable
notifications from the UPS, and keep only the polling) to the ups.conf
definition, and restart the driver to see if it's better?
- can you forward the outputs from mge-shut too (if possible with and
without the notification flag)?

thanks,
Arnaud
