Hi all, 
I'm writing to the list because i have a serious problem on some
Poweredge R310 server.

On this server it is install debian 6 , kernel 2.6.32-5-686-bigmem
Nothing specially running on this server, some php script and a rrd
files.

Problem happen on all 3 server, randomly and without any crash
information, just freeze... nothing on the console. Crash happen in just
one day or sometimes after 2 or 3 days... but 3 server... so every day I
have a crash!

I suppose there are some incompatibility due to 32bit OS version.

Looking on the compatibility page on dell website i can see that only
RedHat 5 have a 32bit version certified and a strange things about
incompatibility with windows 2003

I have try to disable C state on cpu from bios and finnaly boot with
grub option:
apm=off noapic acpi=off

I dont know exactly whats happen i really need help.

PS i cant switch to 64bit due to rrd database created on 32bit
architecture.

Thank you for your help

regards
Francesco
