tomcat"闪退"问题

[springGun]

之前我有发帖询问 tomcat "闪退"问题,这个一直没得到解决 .
昨天又重新查询了下日志,发现 tomcat 手动 shutdown 后 ,日志提示有大量线程未关闭,那么这和 tomcat"闪退"有必然关系吗?
"闪退"指的是 tomcat ,jvm,linux 无日志提示异常.

这个…根据你说的，没什么头绪，还是找 log 看看吧

[defunct9]

开 ssh 我上去看看

日志都不贴，怎么看

我的 Springboot 服务有过 190 多个线程运行的情况。但是服务没有挂掉，只是接受请求很慢。20 分钟的样子。楼主这种情况没见过哇

[woscaizi]

和你的代码有关系，检查代码有没有子线程或者网络连接只有启动逻辑没有关闭逻辑。

没有日志是不是因为日志等级高。检查 tomcat/logs/catlina.out 的内容。

[woscaizi]

@rim99 应该是 cpu 和内存占用高了，所以慢吧。htop 检查资源占用情况。

刚看到的，之前 V2EX 另一个帖子也有回复提到过这个

[shawshi]

我以前遇到过，以及存在相应的问题
1. jar 包冲突（ logback 的日志）
2. tomcat 启动 是否哪个任务占用过多资源过多，导致服务挂掉。
3. 将日志级别调成 debug，分析日志慢慢找。

[pmispig]

一般是 oom kill 了

[ntdll]

检查一下，在退出之前是否 tomcat 占用了大量资源？如果是的话，可能是由于系统资源不足导致系统杀进程，所以 tomcat 没有任何提示。

之前碰到过一个实习生写的，文件句柄只管开，没有关，然后跑着跑着，tomcat 就被系统杀掉了，也是没有任何提示。

这不是内存问题么。。。根源找不到还怎么分析判断

[rim99]

@woscaizi 谢谢回复。检查了，不是 CPU 内存。居然是磁盘满了。然后拉取 Git 仓卡住了。

[sutra]

dmesg 看看是不是有错误信息
