Kdump replaced the deprecated Linux Kernel Crash Dumps (LKCD) tool, which also wrote the contents of memory upon a crash. [11] Kdump presents a more efficient, scalable utility than LKCD. [12] kdump functionality, together with kexec, was merged into the Linux kernel mainline in kernel version 2.6.13, which was released on August 29, 2005. [13]
Analysts of crash dumps from Linux systems can use kdump or the Linux Kernel Crash Dump (LKCD). [10] Core dumps can save the context (state) of a process at a given state for returning to it later. Systems can be made highly available by transferring core between processors, sometimes via core dump files themselves.

When a bug check is issued, a crash dump file will be created if the system is configured to create them. [2] This file contains a "snapshot" of useful low-level information about the system that can be used to debug the root cause of the problem and possibly other things in the background.

Under Windows NT, the second and third sections of the screen may contain information on all loaded drivers and a stack dump, respectively. The driver information is in three columns; the first lists the base address of the driver, the second lists the driver's creation date (as a Unix timestamp ), and the third lists the name of the driver.

ProcDump is a command-line application used for monitoring an application for CPU spikes and creating crash dumps during a spike. [2] [3] The crash dumps can then be used by an administrator or software developer to determine the cause of the spike.
In certain cases, a cold boot attack is used in the discipline of digital forensics to forensically preserve data contained within memory as criminal evidence. [3] For example, when it is not practical to preserve data in memory through other means, a cold boot attack may be used to perform a dump of the data contained in random-access memory.
