The servers were bought at the same time from the same vendor, though I wouldn't be surprised if there were some slight differences.
uname -a results in the following: Linux webpac.osl.state.or.us 2.6.18-92.1.18.el5.centos.plusPAE #1 SMP Wed Nov 26 08:17:45 EST 2008 i686 i686 i386 GNU/Linux _____ From: Stephen John Smoogen [mailto:[email protected]] To: Red Hat Enterprise Linux 5 (Tikanga) discussion mailing-list [mailto:[email protected]] Sent: Tue, 30 Dec 2008 22:08:06 -0800 Subject: Re: [rhelv5-list] 4 GB not recognized after PAE kernel upgrade On Tue, Dec 30, 2008 at 10:52 PM, Chris Adams <[email protected]> wrote: > I am running RedHat 5 on a 32 bit system with 2 GB RAM .

Well the first thing is to make sure the servers are identical... make sure the BIOS version and BIOS settings are exactly the same. I had a set of boxes where the BIOS's were identical but for some reason the shipped settings were different and RAM would not show up.
