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.
System dumps Often known as core dumps, these are platform-specific and contain a raw binary dump of the process memory. This dump has a complete copy of the Java heap, including the contents of all Java objects in the application. OpenJ9 tools are available to process the system dump into a readable format for analysis. Garbage collection data
Many programming languages have mechanisms designed to avoid segmentation faults and improve memory safety. For example, Rust employs an ownership-based [2] model to ensure memory safety. [3] Other languages, such as Lisp and Java, employ garbage collection, [4] which avoids certain classes of memory errors that could lead to segmentation ...
An example of an uninformatively named constant is int SIXTEEN = 16, while int NUMBER_OF_BITS = 16 is more descriptive. The problems associated with magic 'numbers' described above are not limited to numerical types and the term is also applied to other data types where declaring a named constant would be more flexible and communicative.

jinfo – This utility gets configuration information from a running Java process or crash dump. (experimental) jmap Oracle jmap – Memory Map– This utility outputs the memory map for Java and can print shared object memory maps or heap memory details of a given process or core dump. (experimental) jmc – Java Mission Control
Related techniques often include various tracing techniques like examining log files, outputting a call stack on the crash, [8] and analysis of memory dump (or core dump) of the crashed process. The dump of the process could be obtained automatically by the system (for example, when the process has terminated due to an unhandled exception), or ...
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]
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;
