![]() ![]() The size of a kernel memory dump will vary based on the amount of kernel-mode memory allocated by the Operating System and the drivers that are present on the system. The list of running processes, state of the current thread and list of loaded drivers are stored in nonpaged memory that saves in a kernel memory dump. ![]() However, it is unlikely that the user-mode process pages would be required since a system crash (bugcheck) is usually caused by kernel-mode code. Since this is a kernel-mode only dump, there are no pages belonging to user-mode processes. : A kernel dump contains only the kernel-mode read / write pages present in physical memory at the time of the crash. Also, this is the default setting on Windows Server systems. Windows NT4 only supported a Complete Memory Dump. Because of the page file requirement, this is an uncommon setting especially for systems with large amounts of RAM. This type of dump will require that there is a page file at least the size of physical memory plus 1MB (for the header). : This contains the entire contents of the physical memory at the time of the crash. There are three different types of dump that can be captured when a system crashes: Clicking on the Settings button brings up the dump file options as shown below. Within this tool, select System Properties - on the Advanced tab there is a section for Startup and Recovery. The settings for the dump files are configured using the System tool in Control Panel. Remember that we are talking about a total system failure here, not an individual application failure. īy default, all Windows systems are configured to attempt to capture information about the state of the operating system in the event of a system crash. Today we're going to talk about the Crash Dump files themselves - the different types of dumps, how the dumps themselves are generated and why you will need a correctly sized page file. With its intuitive graphical user interface, comprehensive security measures, and support for multiple users and operating systems, CrushFTP is an ideal solution for businesses and individuals looking to securely transfer files over the internet.First published on TECHNET on Jan 08, 2008
