50x photograph of magnetic core random access memory from a 4 KiB memory plane. In computing, a core dump, [a] memory dump, crash dump, storage dump, system dump, or ABEND dump [1] consists of the recorded state of the working memory of a computer program at a specific time, generally when the program has crashed or otherwise terminated ...
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 computing, a segmentation fault (often shortened to segfault) or access violation is a fault, or failure condition, raised by hardware with memory protection, notifying an operating system (OS) the software has attempted to access a restricted area of memory (a memory access violation).
Accessing such memory usually causes operating system exceptions, that most commonly lead to a program crash (unless suitable memory protection software is being used). Using memory beyond the memory that was allocated ( buffer overflow ): If an array is used in a loop, with incorrect terminating condition, memory beyond the array bounds may be ...
The "sawtooth" pattern of memory utilization: the sudden drop in used memory is a candidate symptom for a memory leak. If the memory leak is in the kernel, the operating system itself will likely fail. Computers without sophisticated memory management, such as embedded systems, may also completely fail from a persistent memory leak.
In the event of a kernel crash, kdump preserves system consistency by booting another Linux kernel, which is known as the dump-capture kernel, and using it to export and save a memory dump. As a result, the system boots into a clean and reliable environment instead of relying on an already crashed kernel that may cause various issues, such as ...
The driver of a dump truck learned the hard way that it's best not to tempt fate on a covered bridge originally built before the Civil War. The weight limit on the bridge was 3 tons (2,700 ...
In computing, a crash, or system crash, occurs when a computer program such as a software application or an operating system stops functioning properly and exits. On some operating systems or individual applications, a crash reporting service will report the crash and any details relating to it (or give the user the option to do so), usually to ...
