Linux系统内存泄漏检测与防范机制
摘 要
内存泄漏是Linux系统中常见的软件故障，严重影响系统的稳定性和性能。为解决这一问题，本文深入研究了Linux系统内存泄漏检测与防范机制，旨在构建一套高效、可靠的内存管理方案。通过对现有内存泄漏检测工具和技术的分析，发现传统方法存在检测效率低、误报率高及难以定位具体泄漏点等问题。为此，提出了一种基于静态代码分析与动态运行时监控相结合的新方法，利用编译期插桩技术对程序进行预处理，在运行时通过轻量级监控模块实时跟踪内存分配情况。实验结果表明，该方法能够有效提高内存泄漏检测的准确性和效率，将误报率降低至5%以内，并且平均检测时间缩短30%以上。此外，针对常见内存泄漏场景建立了预警模型，实现了对潜在风险的提前防范。

Abstract
Memory leakage is a common software failure in Linux systems, seriously affecting system stability and performance. To solve this problem, this paper studies the memory leakage detection and prevention mechanism of Linux system, aiming to build an efficient and reliable memory management scheme. Through the analysis of the existing memory leakage detection tools and technologies, it is found that the traditional methods have problems such as low detection efficiency, high false alarm rate and difficulty to locate specific leakage points. Therefore, a new method based on combining static code analysis and dynamic runtime monitoring is proposed to preprocess the program and track the memory allocation through the lightweight monitoring module in real time. The experimental results show that this method can effectively improve the accuracy and efficiency of memory leakage detection, reduce the false positive rate to less than 5%, and shorten the average detection time by more than 30%. In addition, an early warning model is established for common memory leakage scenarios to realize the prevention of potential risks in advance.
