The HP DL360 G5 Kernel Panic dance

This is part rant, part message in a bottle. So my current place of work has standardized on the HP platform, specially, using HP DL360 G5's for both web and database platforms to great success! Until recently... I'm not sure if it's their production line, or whathaveyou, but running apache 2.2.5+php5.2.5 in a production environment makes these things kernel panic, throwing an MCE exception, nearly the same memory banks each time, and then HP's watchdog will reboot the server. Nearly 50% of our 100+ server deployment has this issue. Not surprisingly, HP hardly cares in spite of us using RHEL4u4. Could it be a huge problem with their production line that they shoved under the rug. Is it because of some strange way we are using apache? We've yet to see it in our MySQL cluster. Who knows. What I do know is that it's maddening. Of course like a good production environment of our scale, I know of each reboot, and each alert fills up my inbox all day, it's simply maddening! Maybe HP does have a big problem. Maybe we will solve it. Hopefully someone will stumble upon this and say "hey! yeah I have that problem too!"
