背景

在开发测试环境发现一个奇怪的情况，因查询100w条数据导致OOM，导致服务不可用，java应用是正常的，并没有因为异常退出。

• pod配置：2C1G
• jdk1.8
• spring-boot-starter-web：2.3.12.RELEASE

排查

使用ps -ef 查看进程是否存在，java进程正常。

使用 jstat -gcutil pid 1000 命令查看内存请求，发现FGC一直在飙升。

使用TOP命令发送java线程CPU飚高

导出dump文件定位业务问题，使用MAT工具定位问题

查看日志文件，发现OOM了

思考

为啥OOM会导致tomcat应用假死了？

过了一段时间后，内存成功被释放，也不再FGC了

telnet 命令 进去后退不出了，就是套接字成功创建，但是不接收数据请求

tomcat 问题排查

查看tomcat的核心线程是否正常

• ClientPoller

• Acceptor

通过jstack 命令检查线程信息

• 正常应用

• 异常应用

发现poller线程挂了。

• Acceptor线程用来处理accept事件的，创建tcp链接，并把FD注册到epoll中。
• Poller线程，从epoll中获取read，write事件进行处理。

所以poller线程挂了，telnet只是建立了连接，没有任何响应如上面截图所示。

源码分析

Poller
