kexec kernel automatically reboots before copying entire vmcore file
i am using 4.9 kernel, i installed kexec and kdump related utilities, now when kernel crashes it boots the new kexec configured kernel. when it boots i try to copy 256Gig /proc/vmcore file to local drive, but after copying only around 3GB system reboots automatically. I tried copying vmcore file through SCP but facing the same issue, system reboots automatically. Please suggest if someone knows how to resolve this.
