Hi, I'm happy to ask developers for help , I'm really confused for my crash error. My computer room is running 60 nodes,OS: suse 11 sp1 x86_64 Kernel:2.6.32.12-0.7-default Crash:crash-5.0.1-1.5.5 recently , server often kernel crash, Kdump service dump the vmcore in /var/crash/happen-date/vmcore, I installed the kernel-debuginfo so that check out why crash ,but I got this: linux:~/bb # crash -d8 vmlinux-2.6.32.12-0.7-default vmlinux-2.6.32.12-0.7-default.debug vmcore crash 5.0.1 Copyright (C) 2002-2010 Red Hat, Inc.

Any other infomation need I provide, please tell me ,I'll reply as soon as possible.
