Hi,
have the same issue with one (for now, thank god) DL380 G5. Pulling power cords helped only for short while. CPU temp was back to 255C shortly.
Then I upgraded to latest PSP, which is now 8.7 (was on 8.2.5 before that). Still the same, BUT with a difference. As I disabled ASR before (to prevent server restarting), "restart daemon" finally noticed that and now I can have health monitoring active, without server restarting every 10 minutes. :)
So, HP - what's up? Any reply? My board sensor defective? It probably wont get replaced for free, right. :/
Is anyone from HP actually reading this? As this is HP.com forum....
About installing updated HP Health (8.7) from HP's repository (found info on icinga wiki):
## Add repository to apt/sources.list:
deb http://downloads.linux.hp.com/SDR/downloads/ProLiantSupportPack/ squeeze/current non-free
## Add package signature key:
wget http://downloads.linux.hp.com/SDR/downloads/ProLiantSupportPack/GPG-KEY-ProLiantSupportPack -O - | apt-key add -
apt-get update
apt-get install hp-health hpacucli
P.S. If running Debian, I do recommend removing old 'hp-health', mine did act up and would not upgrade. :)
