Memory management method and device

Abstract

The invention provides a memory management method and device. The method comprises: according to a memory application result of a current process, a memory application failure frequency statistical value Z of the current process is adjusted; and when Z exceeds a preset failure frequency threshold value, restarting the current process. According to the method, frequent restarting of the process canbe avoided as much as possible.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a memory management method and device. Background technique [0002] For programs written in C / C++, due to the lack of a garbage collection (garbage collection, GC) mechanism, the memory occupied by the process will not be recovered. When a memory leak occurs in the process executing the program written in C / C++, the process More and more memory will be occupied, causing the system to run slower and slower, and even cause the system to run out of memory (OOM) in severe cases. [0003] In order to solve the above problems, the traditional solution adopts the cgroup mechanism in the linux system (the mechanism manages and controls the behavior of the system resources used by the process in the form of grouping) to group all processes, create multiple memory management and control groups, and create multiple memory control groups for each The memory control gro...

Problems solved by technology

[0004] In the traditional solution, as long as a process in the memory control group fails to apply for memory, the process in the memory control group is restarted, which may cause frequent restarts of the process
