Abstract

The embodiment of the invention discloses a method and a device for processing operating system exceptions. The method comprises the steps of operating corresponding core detection threads; leading each core detection thread to enter a circulation calling procedure, updating time counting of a central processing unit in a circulation to be current time, using the core detection thread corresponding to one central processing unit to detect time counting of another central processing unit, and judging whether a difference value between the current time of the one central processing unit and the time counting of another central processing unit is larger than a first setting value or not; and conducting exception processing if the difference value is larger than the first setting value. By means of the mode, the method and the device can detect the operating system exceptions caused by the fact that deadlock happens or a plurality of central processing units in an operating system.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for processing exceptions in an operating system. Background technique [0002] Currently, the Linux operating system is widely used in the field of telecommunications, especially in key services in the field of telecommunications. In these applications, users increasingly require the Linux operating system to have strong fault detection capabilities and the ability to quickly restore services after a fault occurs. When the operating system fails and cannot resume business for a long time, it will cause economic losses to users and reduce user satisfaction with product quality. [0003] The Linux operating system itself has the function of KDUMP (Kernel Dump, the process of saving the memory of the abnormal operating system to the disk after the operating system is abnormal). When the action taken after) or OOPS (refers to the operating system kern...
