Abstract

The present application provides a method and device for reminding shared memory leaks. A method for reminding a shared memory leak, comprising: monitoring the address space of the target process after receiving a message that the target process is successfully started; The size of the address space occupied by the shared memory, and the information of the shared memory attached to the target process; according to the size of the address space occupied by each shared memory attached to the target process, and / or the target process attached The shared memory information of the target process is used to determine whether there is a shared memory leak in the target process; if so, a reminder is given. The application can realize the automatic monitoring and reminding of the shared memory leak, so that the system administrator can find the shared memory leak 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...
