The core dump feature is a mandatory telemetry feature for the Deep Space segment as it has been proven to minimize system diagnostic costs. [citation needed] The Voyager craft uses routine core dumps to spot memory damage from cosmic ray events. Space Mission core dump systems are mostly based on existing toolkits for the target CPU or subsystem.
IPCS (Interactive Problem Control System) is a z/OS component which can analyze unformatted application dumps dumps (SYSMDUMP) or snapshot dumps, or stand-alone system dumps (SADMP). IPCS can inspect any storage address in the dump and format system control blocks, providing labels for fields. It can be run interactively or as a batch job. [2]
A Windows driver, for example kprocesshacker.sys, can be used to run programs such as cmd.exe as internal accounts, also providing access to LocalSystem. In certain versions of the Linux kernel it was possible to write a program that would set its current directory to /etc/cron.d , request that a core dump be performed in case it crashes and ...
The kernel can generate signals to notify processes of events. For example, ... Terminate (core dump) – Abnormal termination of the process. Additionally ...
For example, many Unix operating ... function was also enhanced to dump various forms of debugging information to the console. Causes ... Core dump; Blue screen of death;
In general, their primary usage is to extract text from the memory dump. [2] Many operating systems provide features to kernel developers and end-users to actually create a snapshot of the physical memory for either debugging (e.g. core dump or Blue Screen of Death) purposes or experience enhancement (e.g. hibernation).
A core file may be generated to aid debugging, and other platform-dependent actions may also be performed. For example, Linux systems using the grsecurity patch may log SIGSEGV signals in order to monitor for possible intrusion attempts using buffer overflows.
Core memory controllers were designed so that every read was followed immediately by a write (because the read forced all bits to 0, and because the write assumed this had happened). Instruction sets were designed to take advantage of this. For example, a value in memory could be read and modified almost as quickly as it could be read and written.
