Abstract

In one embodiment, a method of a kernel dumper module includes generating a dump file associated with a kernel when the kernel crashes, storing the dump file to a functional memory upon applying an overwrite protection to a core dump of the dump file, restarting the kernel through a warm reboot of the kernel such that the core dump is not erased from the functional memory, and transferring the core dump to a system file using the kernel.
