[cisco-voip] OS 2000.4.2 sr7 upgrade

[Simon, Bill]

Yesterday I attempted an upgrade on our cluster from 2000.2.7sr4 to 2000.4.2
then applied sr7.

CallManager version is 4.1(2)sr1.  Cluster hardware all around is HP DL-380
G3 (like MCS-7835 or 7845)

The short story is that after the upgrade and a few hours of frustrating
poor or non-existent phone service, we bailed out to a set of mirrors taken
the day before.  The main symptom of a sick CM cluster was that on the
subscribers where phones registered, CPU loads upon boot went to 100% and
stayed there.  CCM.EXE was the process using most of the CPU.  The high load
caused failed registrations, incredibly slow response times on phones, VM
and gateway ports registering and then going unregistered, and other
weirdness.

After an hour and a half talking to TAC on a P1 case we were unable to wait
any longer and had to bail out.

The case is still open and we're hoping to get to the bottom of it but I'm
putting this out there in case any of you have seen something like this,
have feedback/thoughts, etc.
