[Nut-upsuser] UPS suddenly powered off

Hi,

I'm using a gamasonic UPS with a megatec driver since two years with no 
problem.
I'm running a Linux server Debian Etch 4.0 and the nut package is ( 
taken from dpkg -l nut )

ii  nut                          2.0.4-4                      The core 
system of the nut - Network UPS Tools

Today morning I found the UPS powered off. I had to manually power it on.

I found the following messages in /var/log/syslog :

Nov 12 20:34:18 pc5 upsd[2372]: Data for UPS [gamasonic] is stale - 
check driver
Nov 12 20:34:20 pc5 upsd[2372]: UPS [gamasonic] data is no longer stale

And after that there are no other messages, until the power up messages 
( so I must conclude that the server was suddenly powered off without 
doing a nice shut down ).

There are two possibilities: the UPS suddenly shut itself down ( very 
unlikely as there was no power blackout ) or the nut driver mistakenly 
gave the UPS a power off command.

Thanks in advance for helping me to diagnose the problem.
