In computing, a core dump, crash dump, memory dump, or system dump 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 abnormally. In practice, other key pieces of program state are usually dumped at the same time, including the processor registers, which may include the program counter and stack pointer, memory management information, and other processor and operating system flags and information. A snapshot dump (or snap dump) is a memory dump requested by the computer operator or by the running program, after which the program is able to continue. Core dumps are often used to assist in diagnosing and debugging errors in computer programs.

Managing process state information in an operating system environment
InactiveUS20050210077A1Excessively generatedNon-redundant fault processingProgram controlCore dumpOperational system
A technique for managing process state information involves pushing process state information from the kernel space to the user space in the event of an application crash and generating a core file at the user level instead of at the kernel level. Handling the process state information at the user level instead of at the kernel level provides more flexibility in the generation and management of a core file as compared to systems that use kernel code to generate and manage the core file. A core dump application at the user level can be programmed to forward the core file to another system that has permanent storage capacity available. Additionally, the core dump application can be programmed to compress the process state information and / or to extract only certain information from the process state information while generating the core file.

In particular embodiments, a monitoring processor may receive an interrupt from status monitoring logic associated with a monitored processor that has experienced an error. Interrupt logic at the monitoring processor may interrupt the monitored processor to initiate a standby mode of operation in the monitored processor. Core dump logic at the monitoring processor may retrieve a core dump from a memory associated with the monitored processor via a communication channel connecting the monitoring processor to the monitored processor or to the memory. Other embodiments are disclosed and claimed.

Failure Detection and Fencing in a Computing System
A method, computer program product, and system for detecting and fencing off a failed entity instance so that failover time in the computing system is reduced. Upon detection of a failed entity, for example a failed process, a signal handler invokes an operating system interface to fence off the failed instance from modifying its persistent state, so that the entity may be re-instantiated prior to termination of the failed instance. This approach reduces failover time and eliminates split-brain problems without compromising access to the failed instance to obtain diagnostic information, core dumps, and the like.

Method for capturing core dump of a service module
A bootstrap program is loaded into an area of memory previously occupied by a run time program in a service module. The bootstrap program is loaded after the service module is reset due to an error. The service module does not have a persistent storage. The bootstrap program captures a memory image of the memory. The captured memory image of the memory is compressed and transferred to a control module to be stored in a persistent storage of the control module. The control module receives captured memory images from one or more service modules.

System and method of selection and communication of a disk for storage of a coredump
ActiveUS20050177764A1Reduce wasteRapidly takeNon-redundant fault processingRedundant hardware error correctionCore dumpFile server
This invention provides a system and method for selecting and communicating a single disk (a “coredump disk”) for use in a coredump procedure by a failed file server (or filer). A selection method on the failed filer determines the “best candidate” coredump disk according to a predetermined set of criteria. For example, the available disks that can receive coredump data are located and ordered so as to prefer disks that best match the coredump data size requirement, are least likely to be needed for normal service by the server; and require the least preparation to receive coredump data. Appropriate attributes on the selected coredump disk are written to indicate that a coredump is in progress, and the location of the coredump data. Upon reboot of the failed filer (or takeover by a cluster partner), the coredump disk is identified and the coredump data recovered by reading back appropriate attributes.
