Redhat 2.1 AS Memory Limit?
I have a customer with an HP DL380 G4 server running Redhat 2.1 AS that has 4GB memory installed. They want to upgrade in the server to the maximum of 12GB using (6) 2GB DIMMs. I can do this for them, but I read somewhere that Redhat 2.1 has an upper memory limit. Or you need a kernel patch to use memory above a certain range. Does anyone out there know the details of these restrictions?
Here is the Redhat release and kernel info from the server:
# cat /etc/redhat-release
Red Hat Linux Advanced Server release 2.1AS (Pensacola)
# uname -a
Linux server003.mydomain.net 2.4.9-e.57smp #1 SMP Thu Dec 2 20:51:12 EST 2004 i686 unknown
Thanks!

refresh(hardware) or refresh(rpmlist)
new_systemid This action is used by the RHn Backend to update the Digital
system ID of this machine with a new one.
update_packages This action will trigger rhn_check into running a package
update for a list of packages queued from the Red Hat Network.
rhn_check will use modules from the up2date client to download
the packages, solve dependencies and install the on the system.
