问题分析：
问题来源是客户通过闲鱼找到了我这边进行问题的排查，给我发了一个报错日志，让我帮忙分析。
首先他的项目比较老，很多年以前开发的软件，但是具体做什么业务我不知道。下面来看日志的报错分析。
问题：tomcat自动关闭，频繁关闭。
jvm报错的一个错误信息：

错误分析
-
异常线程:
错误日志中的JavaThread "C2 CompilerThread2" daemon表示这是 Java 的 JIT 编译器线程崩溃了。C2 CompilerThread2是 HotSpot JIT 编译器的线程，它负责编译 Java 字节码为机器码。如果 JIT 编译器遇到问题，可能会导致 JVM 崩溃。 -
指令和崩溃点: 在日志中，崩溃指令位于
jvm.dll中，具体位置是0x000000006f9a8688。这个指令处在 JVM 的本地代码部分，通常意味着有 JVM 内部的缺陷、驱动问题或者库文件冲突。 -
调用栈:
msvcr100.dll是 Microsoft Visual C++ Redistributable 的一个 DLL 文件，通常是由 C++ 编写的程序依赖的。如果你的程序使用了某些本地代码或与 C++ 库有交互（如 JNI 调用），这个 DLL 可能会受到影响。KERNEL32.DLL和ntdll.dll是 Windows 操作系统的系统级 DLL，通常表示系统底层问题。
-
可能的原因:
- JIT 编译器缺陷：某些特定的字节码或代码模式可能触发了 JIT 编译器的 bug，导致内存损坏或无效访问。
- 操作系统或硬件问题：比如内存损坏、硬件冲突或者操作系统本身的问题（如 Windows 更新导致某些系统库出问题）。
- 依赖的本地库问题：如果你的程序依赖某些 C/C++ 库，或者与某些本地代码交互，可能是本地库出现了问题。
当然从上面来看不一定是可能的问题，上面只是做一个普通分析，通过看jvm回收的日志来看确实是正常的.

这个这个错误一看就是有人在尝试通过非法字符篡改请求接口，尤其是当攻击者试图利用一些不规范的 HTTP 请求来攻击系统时，因为服务端的编码都是uft-8的字符，走客户端不可能出现不一样的编码，所以这很明显了是在url非法请求，这种直接去操作人家接口很明显了。

这个错误就更明显了一直参数越界了，说明人家在一直篡改参数请求，没有按照你的规范操作，导致数据对不上了直接报错了，这个错误你觉得不明显你说不是别人在请求，来看下面的问题。

这个错误足够明显了吧，你要再说不是别人在请求篡改说不过去了吧，我后台定义好的数据格式，怎么就会报json序列化异常呢？足够明显了吧。

连接的管理不当导致的，通常发生在一个连接被分配后，没有及时释放，导致后续的请求不能正常获取到连接。这种问题可能出现在并发请求、连接池管理不当等场景。
看到这里上面的问题我想你有答案了没错改代码：
接口加签名，接口做幂等，通过token令牌或者 验签访问接口，保证接口不被重复请求，数据不会重复提交这是最靠谱的。
但是上面错误起码能给80%的把握定位是别人请求，但是具体的代码还是要通过arthas 进行调优查看的。
cpu跑满了 可以看到，这明显就有问题了，这里arthas就不细讲了。但是一定位就是线程池的问题，有线程没有释放，一直占用资源导致cpu上来了，然后tomcat关闭掉了，下面这个也是因为代码问题提交的阻塞。
问题也定位到了所以改代码吧，具体的分析过程就是这样，当然这也不是第一次去排查线上问题了，遇到问题首先要分析问题根本原因，日志必须要看，然后再去定位代码，问题也就迎刃而解了。当然大家如果要是有问题可以去闲鱼搜索：小杨互联网 ←←
