Use a PAE enabled kernel. 3200MB HIGHMEM available. 896MB LOWMEM available. Installing a PAE kernel (kernel-pae) kernel seems to be the recommended fix for this. Alternatively, adding mem=4096 to the kernel boot parameters may also work.

Installing the PAE kernel works in that you get all 4 GB of RAM. However, the network driver (e1000e) isn't included in the kernel package. Adding mem=4096 does *not* work.

we should also be able to install a 64bit kernel, but we would then be running all 32bit binaries with the kernel 32bit emulation.

We're running 32-bit CentOS on these machines.

I got the e1000e network driver compiled for the PAE kernel, so it's just a matter of installing that everywhere.

linux slaves 1-13,25 have the kernel-PAE-i686 package installed. only slave01 has it enabled as the default kernel in /boot/grub/menu.lst

there's an rpm in /root on mv-moz2-linux-ix-slave01 called e1000e-1.1.2PAE-1.i386.rpm. This should be installed on all the slaves prior to rebooting into the PAE kernel. 'depmod -a 2.6.18-8.el5PAE' should also be run after installing this rpm and before rebooting.
