netty-common-4.1.43.final.jar版本有内存泄漏吗

一、 产生的异常 

当时是服务器访问不到服务了，上去一看，无法申请资源OutOfDirectMemoryError了，内存级别的东西让人一阵头大，赶紧在线下模拟，

1. 减少分配的堆外内存，打开Netty的监测工具等有助于复现的配置和检查的信息

-XX:MaxDirectMemorySize=2M
-Dio.netty.leakDetection.acquireAndReleaseOnly=true
-Dio.netty.leakDetectionLevel=paranoid
-Dio.netty.leakDetection.targetRecords=50
-XX:-OmitStackTraceInFastThrow
-XX:NativeMemoryTracking=detail

Netty的内存泄漏检测分为四个级别：

  • DISABLED - 完成禁止检测内存泄漏，这个是不推荐。
  • SIMPLE - 如果buffer中出现1%的内存泄漏，打印错误日志，就是上面那样。但是日志是看不到详细在什么位置出现了内存泄漏。鉴于性能考虑，这个是在生产环境中默认使用。
  • ADVANCED - 如果buffer的1%出现内存泄漏，打印错误，并且输出详细的内存泄漏信息。
  • PARANOID - 这个和ADVANCED输出的内容是一样的，但它会对每一次请求的buffer做检查。很适用于调试和单元测试。

建议

1、为了今早的发现问题，强烈建议在开发调试过程中，把检测级别设为PARANOID，设置：

io.netty.leakDetection.level=PARANOID

二、 检查内存泄漏点位

由于有点多，还特意把检测的详细条数改到了50。

挨个查看是不是有自己写的代码或者熟悉的代码，看了一遍没认识的，完蛋这会麻烦了，各种找资料（百度），上官网（Netty的Issues · netty/netty · GitHub）（gateway的LEAK: ByteBuf.release() · Issue #26937 · spring-projects/spring-framework · GitHub）各种查，大部分都是版本问题但是都是老版本，我看我的都是新版的了咋还有，DEBUG后发现总是在请求进来时申请一次2048的，在后续的处理中涨涨降降最后就是这点没释放

  1. 2023-12-19 09:33:12.933 [reactor-http-nio-35] ERROR io.netty.util.ResourceLeakDetector - LEAK: ByteBuf.release() was not called before it's garbage-collected. See https://netty.io/wiki/reference-counted-objects.html for more information.

三、 修复

别看上面一堆很长，关键的就是几个点：

Hint： 开头的

Spring的一些

如果有自己的代码记得释放就好，我的没有就需要对比试用版本和泄漏点是不是有使用没有释放，或者释放未成功。

第一次试着升级了gateway的版本但是无效，后来想单独升级会不会有冲突，回滚后一起升级的Springboot+SpringCloud，试运行后还是不行，查看依赖时发现Libraries中旧版Jar包引入在未删除，造成了冲突，删除后，Maven刷新，在运行一切就正常了。

原版本：

<spring-boot.version>2.6.13</spring-boot.version>
<spring-cloud-alibaba.version>2021.0.5.0</spring-cloud-alibaba.version>
<spring-cloud.version>2021.0.5</spring-cloud.version>

升级后版本：

<spring-boot.version>2.6.15</spring-boot.version>
<spring-cloud-alibaba.version>2021.0.5.0</spring-cloud-alibaba.version>
<spring-cloud.version>2021.0.8</spring-cloud.version>

推荐堆外内存监控程序和检查的一些资料可以参考：

Spring Boot各版本与Java版本的对应兼容关系，与构建工具（Maven、Gradle）版本的对应兼容关系，对servlet 容器的支持-CSDN博客

还有一些找不到了，每个里面找个有用的汇总起来解决；希望可以帮到有需要的朋友
