Crash Dump Files in Windows®
What are the crash dump files in Windows and how to solve this issue?
Crash dump of files allow users to save the information in order to debug it later. Crash dump comes to use when you do the testing of file without the source files. When any such crash happens, saving of dump file and debugging could be done in the same or other system. It is seen that Windows enabled PCs are now configured to get the information about the state of Operating System even in the event of crash. All the settings which are present for dump files are now configured by using the ‘System Tool’ from ‘Control Panel’. In the ‘Advanced’ tab, there would be a section for ‘Startup and Recovery’. While you click the ‘Settings’ button, it would then bring the files of dump with options. There would be mainly three types of dump files and they could be retrieved while crashing of system occurs.
Below given points would talk about different crash dumps which are being related to Windows:
- Complete memory dump
- Kernel memory dump
- Small memory dump
Complete memory dump
This type of crash dump would have got the full contents of the physical memory during the time of the crash. This type of crash dump requires the page file having the size of a physical memory and an additional 1 MB for the header also. Since, this page file requirement is present, this type setting are very uncommon especially in case of systems with large amount of RAM. This memory dump is being supported by the Windows NT4 only. On Windows Server computers, this is one of the default settings.
Kernel memory dump
This type crash dump would have only the kernel-mode write/read pages that are in physical memory during crash. No pages are present which correspond to user mode processes since it is dump with kernel only. The list of loaded drivers, running processes and the state of the current thread are being stored in the nonpaged memory and that would save in kernel memory dump. The size needed for this dump would vary with kernel memory for each operating system and also the drivers in computer.
This crash dump is also called as mini dump and is about 64Kb while for 64-bit systems it is about 128 KB. This would contain list of all loaded drivers, stop code, current process and thread information and the kernel stack for thread also which caused the crash. This type of memory dump file could be very useful when system has limited hard disk space.
