Abstract
A method, system and a computer program product for managing a computing system crash. Memory of the computing system is separated into at least two classifications, referred to herein as a dumpable area and a non-dumpable area. Upon detection of an operating system crash in the computing system, an operating system module prevents a dumping operation of the memory, including preventing access to the dumpable memory area, and divides the non-dumpable area into a new dumpable area and a new non-dumpable area. At such time as the operating system is rebooted, the dumping operation is initiated and completed in the dumpable area, and resumed operations use the non-dumpable area.
Claims11
A method for managing a computing system crash, the method comprising:
- dividing a memory of the computing system into a first area and a second area;
- detecting an operating system crash in the computing system;
- and
- responding to the detected crash, comprising:
- initializing a dumping operation of the first area;
- dividing the second area into a new first area and a new second area;
- freeing the first area, the freed first area becoming freed memory;
- rebooting the operating system using the new second area,
- wherein access to the new first area is blocked until the rebooting is completed;
- and
- resuming one or more operations following the reboot, the resumed operations using the new second area.
