Dave, Thank you for getting back to me so quickly. I have tried different ways to start crash but none is working. I have downloaded kernel-bigsmp-2.6.5-7.321.i586.rpm from Novell to match the version of the dump. This package includes the following files: config-2.6.5-7.321-bigsmp System.map-2.6.5-7.321-bigsmp Kerntypes-2.6.5-7.321-bigsmp vmlinux-2.6.5-7.321-bigsmp symtypes-2.6.5-7.321-bigsmp vmlinuz-2.6.5-7.321-bigsmp symvers-2.6.5-7.321-i386-bigsmp I don't believe Novell provides a kernel-debuginfo package for SLES 9 or earlier version and I could not find it on their web site. What I have tried so far are all done on RHEL systems because SLES 9 does not come with crash. Do I need to run crash against an SLES dump on a compatible SLES system? A compatible system I mean the same architecture. When I tried it on RHEL X64, it complained machine type mismatch.
