[PLUG] spontaneous reboots

[Barbara Pfieffer]

I once ran a NT network in Chicago. WHen I looked at the logs, everyday 
at 6am, the UPS kicked in for like 5 seconds. What I finally found out 
was that at 6am, the local electric company switched from one type of 
power plant to others and caused a really brief interruption. Decreased 
the sensitivity on the UPS and it went away.
