At a start, I'd suggest upgrading to the latest eratta kernel, as it fixes many issues.
You may also need to use a differently-compiled kernel. By default, the latest eratta kernels have the kernel flag 'CONFIG_HIGHMEM4G' set on to support between 1 and 4GB of memory. It's turned off in all but the i686 series of kernel packages in the release set.
Stuart is giving a good idea. verify if your kernel supports bigmem. The command free will give you information to see if your kernel is using the hole RAM.
Another thing you may see is if your job has some issues regarding memory parameters that you may configure at startup like shmmax, shmmni and shmall. I guess you have to look for that kind off information on the software manual.
You don't mention what distro. If you are using Red Hat Enterprise Linux 3.0, you need to use one of the hugemem kernels from RHN. The description of one says:
This package includes a kernel that has appropriate configuration options enabled for Pentium III machines with 16 Gigabytes or more of physical memory.
