Abstract: A method and system for collecting data for diagnosing a failure of a computer hardware device. After an indication of the failure of the computer hardware device that results in a full system crash is received, an address translation table of a central processing unit (CPU) of the computer hardware device is collected. A format of call stack frames of an operating system (OS) image of the computer hardware device is retrieved. Based on the collected address translation table and the retrieved format of the plurality of call stack frames, the call stack frames are retrieved and output to a computer file.

Abstract: Flight data indicating a history of what has happened in a virtual memory system's programs is recorded. Memory residency of symbolic information associated with the flight data and is determined, and a determination is made whether all items needed to record the symbolic information are available without disk reads in the virtual memory system. If all items needed to record the symbolic information are available in the virtual memory system without disk reads, the symbolic information is recorded in-line at the time of recording flight data. If all items needed to record the symbolic information are not available without disk reads, only the virtual memory handles are recorded in-line at the time of recording flight data.
