The method stores data characteristic of the status of a computer given a malfunction that requires a subsequent restart of the computer. The computer status data is thereby continuously stored in the main memory of the computer and is read out therefrom and transferred onto a data carrier before the formatting of the main memory given the restart of the computer after the malfunction. A securing of the computer status data for error analysis and elimination can also be achieved with the inventive method given an immediate restart of the computer, so that the method can also be utilized in fail-safe systems with automatic start-up, for example in communication switching systems.

Method for storing computer status data given a malfunction that requires a subsequent restarting of the computer

The specified monitoring program enables the recognition of endless loops or blocked processes in a computer system, in particular in a telecommunication switching system. When such software errors are recognized, error indices can be collected and stored, which enable a later error analysis and removal. The endless loops or, respectively, blocked processes can also be reset in a suitable way, so that no negative effects on other processes result.
