Default How to examine crash dump of Centos Kernel


I have been able to successfully use crash to examine a crash dump of
kernel-PAE-2.6.18-92.1.6.el5 using the following command:

crash /boot/System.map-2.6.18-92.1.6.el5PAE /usr/lib/debug/lib/modules/2.6.18-92.1.6.el5PAE/vmlinux ./vmcore

I then installed the package kernel-debug-2.6.18-92.1.6.el5 and rebooted
with that (there is no PAE debugging kernels in the repository). I
reproduced my crash and collected a crash dump, however when I try to
examine the dump I get the following error:

crash /boot/System.map-2.6.18-92.1.6.el5debug /usr/lib/debug/lib/modules/2.6.18-92.1.6.el5/vmlinux ./vmcore

crash: v2 module syment space malloc (2005518689 symbols): Cannot
allocate memory

I have used ulimit in the shell to set all of the limits to unlimited
and I still continue to have this problems. Any ideas? Is it possible
that I would need a 64 bit OS in order to examine a 4gb crash dump with
symbols and debugging information?

I have the following kernel-debuginfo packages installed:

I am running CentOS 5.2 on a dual Xeon Server with 4gb of memory.
