[8] [self-published source?] A kernel panic is the Unix equivalent of Microsoft's Blue Screen of Death. It is a routine called when the kernel detects irrecoverable errors in runtime correctness; in other words, when continuing the operation may risk escalating system instability, and a system reboot is easier than attempted recovery.
The Blue Screen of Death on Windows XP, Windows Vista and Windows 7, performing a memory dump by default. In the Windows NT family of operating systems, the blue screen of death (referred to as " bug check " in the Windows software development kit and driver development kit documentation) occurs when the kernel or a driver running in kernel ...
Debugging information is saved in NVRAM and written to a log file on reboot. In 10.7 there is a feature to automatically restart after a kernel panic. In 10.7 there is a feature to automatically restart after a kernel panic.
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.
On modern Unix-like operating systems, administrators and programmers can read core dump files using the GNU Binutils Binary File Descriptor library (BFD), and the GNU Debugger (gdb) and objdump that use this library. This library will supply the raw data for a given address in a memory region from a core dump; it does not know anything about ...
Dereferencing any of these variables could cause a segmentation fault: dereferencing the null pointer generally will cause a segfault, while reading from the wild pointer may instead result in random data but no segfault, and reading from the dangling pointer may result in valid data for a while, and then random data as it is overwritten.
objdump is a command-line program for displaying various information about object files on Unix-like operating systems.For instance, it can be used as a disassembler to view an executable in assembly form.
Instead of converting a database dump file to many pieces of static HTML, one can also use a dynamic HTML generator. Browsing a wiki page is just like browsing a Wiki site, but the content is fetched and converted from a local dump file on request from the browser.
