What do I find in a crash dump file?
The .dmp file contains your stop error message, a list of disks mounted when the problem occurred, and detailed information about the kernel, processor, and processes simply because, as well as other information about the type of dump file we are using.
Kernel mode dump files can be parsed by WinDbg. The processor, or possibly the version of Windows on which the dump file was sent, often does not have to match the platform on which KD is to run.
Start WinDbg
To parse the dump file, run WinDbg with the command line parameterki -z:

Fortect is the world's most popular and effective PC repair tool. It is trusted by millions of people to keep their systems running fast, smooth, and error-free. With its simple user interface and powerful scanning engine, Fortect quickly finds and fixes a broad range of Windows problems - from system instability and security issues to memory management and performance bottlenecks.
The -v (verbose mode) personal option is also useful. For a complete list of options, see WinDbg Command Line Options .
If WinDbg is already running and is indeed in standby mode, you can open Crash and write a dump by opening the file | … Select the Open Crash Dump menu command or abort the Ctrl + D keyboard shortcut. Usually, when the Open Crash Dump dialog box appears, enter the full path and error dump file in the File name field, or use the dialog box – select the correct path and file manufacturer. When the file is oriented correctly, select “Open.”
You can also open the dump file after starting the debugger by scrolling through it with Get .opendump and then g with (Go) .
It is possible to debug several file dumps at a particular point in debugging. This can be achieved by adding multiple -z switches to the command line (each followed by a different boot name), or using .opendump to add another file debugger from dump-only targets. To get addFor more information on monitoring a multi-target workout, see Debugging Multiple Targets .
Dump files usually have a .dmp or .mdmp extension. You can use network shares or UNC file names for the kernel dump file.
What does dumpfile mean in Linux crash dump?
DUMPFILE: This is something like the name of the paged memory kernel. CPUS: The number of processors on your current computer. DATE: indicates the time of the failure. TASKS: Indicates the number of commitments in memory at the time of the failure. A task is simply a set of programming instructions that are carried into memory. NODENAME: the name of the most unfortunate hosts.
It is also common to compress split files into a .cab file. If you specify the creator of the file (including the .cab extension) after our -z option, or as an argument to the very good .opendump command, debuggers can usually read dump files directly from the CAB. However, if multiple computer dump data files are stored in the same CAB, the affected debugger can only read from one of them. The debugger will not display any additional CAB files, even if they are symbol files or other files associated with the dump file.
Analyze The Dump File
If you are parsing a core dump or small core dump, you may need to specify the path to the exe image so that it points to any exe files that might have been fully loaded into memory during our own crash.
Analysis of the dump file is similar and allows analysis Host a real-time debugging session. For resources available for debugging kernel-mode dump files, see the Debugger Commands reference topic.
You should start with ! scan in most packages. Extension This command automatically scans the main dump file and can often display a lot of useful information.
.bugcheck (displaying error data for error checking) always displays the error checking code and its parameters. For more information about each error checking that it encounters, see the Error Checking Code Reference .
The following debugger extensions are especially useful for analyzing a kernel mode crash dump:
