Excellent description. That being said the reason I have such a big
honking APC brand UPS is that my company's Logistics department
overbought on a major contract! Rather than paying Inventory Tax on the
extras the Boss sold them to several of us below our Dealer cost! I
have approx. two hours run time but, this outage lasted over three and
1/2 hours while no one was home!
According to my logs I did get a controlled shutdown on all three of my
servers, the two Red Hat ES 4 severs have no problem only my Fedora 13
server. Thus I am leaning more towards a hack that was just waiting for
ANY reboot to pounce!
Especially after I got this:
# rpm -V| --verify *
bash: --verify: command not found
rpm: no arguments given for verify
Something is not right!
