Hi,
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: kernel-debuginfo-common-2.6.18-92.1.6.el5 kernel-PAE-debuginfo-2.6.18-92.1.6.el5 kernel-debuginfo-2.6.18-92.1.6.el5
I am running CentOS 5.2 on a dual Xeon Server with 4gb of memory.
Thanks, Nataraj
