That's the UPS taking care of a line spike.  It's a good idea to turn off
all equipment when that happens.  Especially the printers.  They can take
out the fileserver if they get fried.

Mar 16 06:10:50 anakin upsd[8303]: frequency: 60.00, maxvac: 125.4, minvac: 120.9, voltage: 124.1
Mar 16 06:10:50 anakin upsd[8303]: load: 45.2, recharge: 100.0, temp: 38.7, vdc: 27.60, output voltage: 123.5

123.5V is the most it is willing to put out.  It's taking in 124.1 here.
the max it has recorded up to now is 125.4... I'll watch this for a while,
and if we get more of it, I'll tone down the sensitivity on the UPS.  125 is
reasonable to feed a computer (barely).

Darn... and I thought we had clean power in there.
