Abstract

The application provides a shared memory leak reminding method and device. The shared memory leak reminding method includes: after a message about successful start of a target process is received, monitoring address space of the target process; acquiring, according to the monitoring results, sizes of address spaces used by shared memories attached to the target process in the address space, and information of the shared memories attached to the target process; judging whether the target process experiences a shared memory leak according to the sizes of the address spaces used by shared memories attached to the target process in the address space, and the information of the shared memories attached to the target process; if yes, providing a reminder. The shared memory leak reminding methodand device can provide automatic monitoring and reminding for shared memory leaks so that a system administrator may find the shared memory leaks in time.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for reminding shared memory leaks. Background technique [0002] In a multi-process operating system, multiple processes often need to share data. Usually, a shared memory method can be used to enable multiple processes to share data in the same memory. After a process creates a shared memory, if other processes need to use the data in the shared memory, they can map the shared memory to their own address space, that is, attach the shared memory. When the use is completed, unattach the shared memory. Can. [0003] However, due to programming defects, a process may attach to the same shared memory multiple times, but does not detach the attachment after using the shared memory, which is called a shared memory leak. Moreover, when a process attaches to the same shared memory multiple times, the shared memory will occupy different locations in the a...
