Hi, > Now I updated crash tool, but the issue still exists, It reports as follow: [...] As I remember "crash xen-syms-dbg-4.1.3_02-0.5.1 /mnt/disk/crash/2012-09-30-19\:03/vmcore" should be sufficient. If it still does not work please send me output from following command: # readelf -Wa /mnt/disk/crash/2012-09-30-19\:03/vmcore Daniel -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/crash-utility
