Dear all,
I am having trouble with
MGE Pulsar Evolution 800 Tower UPS.
I use this UPS on several computers under RH9.0 O/S -- and the effect
is the same.
Each computer has two UPS connected: one on ttyS0 (MGE) and the other
on ttyS1 (generic). One UPS is MGE, the other one is usually some
inexpensive generic UPS.
The software I am running is nut-2.0.3.
After starting up the UPS utilities (/etc/rc.d/init.d/ups start), this
is a typical message:
Broadcast message from nut (Tue Dec 26 17:38:35 2006):
Communications with UPS hat_PC_ups@localhost lost
Broadcast message from nut (Tue Dec 26 17:38:45 2006):
Communications with UPS hat_PC_ups@localhost established
...
And this goes on forever. Sometimes the connection is lost, sometimes
it is established. After a while (hours, maybe up to a day) the
mge-shut software disappears from the process list.
I guess maybe pollfreq is too small? But that still does not explain
why mge-shut dies away.
When it works, I get the following output:
