Abstract

The embodiment of the invention discloses a memory recovery method and device, equipment and a medium, which are used for solving the problem of memory leakage caused by the fact that a system is in an operating state for a long time. The memory recovery method comprises the steps of obtaining a process identifier and an actual use physical memory of each process in a running state in a system; onthe basis of a pre-configured memory leakage level table, the memory leakage level of each process is determined according to the obtained actual use physical memory of each process, and the memory leakage level table comprises corresponding relations among process identifiers, memory leakage thresholds and memory leakage levels; and closing part or all of the processes of which the memory leak levels are greater than a first preset level threshold.

Description

technical field [0001] The present invention relates to the technical field of memory management, in particular to a memory recovery method, device, equipment and medium. Background technique [0002] At present, more and more in-vehicle central control systems use the Android system. In practical applications, in order to instantly respond to various control operations (for example, remote control), the in-vehicle central control system generally does not shutdown. [0003] Due to the defects of the memory management of the android system, if the android system is running for a long time, its memory leak problem will be difficult to be repaired. There are some methods for detecting memory leaks in the prior art. These methods usually involve complex calculations and logic processing when detecting memory leaks, and bring additional overhead to the system. [0004] Therefore, there is an urgent need for a memory recovery method to solve the problem of memory leaks caused b...
