Java异常\u访问\u冲突-严格来说是JVM问题？对我来说什么都没有？

这条消息没有看上去那么长-我只在末尾附上了一份冗长的日志报告

大家好

我正在运行一个用Java实现的实验爬虫程序。 最近，在36小时的操作后，JVM崩溃，发出了一个异常访问冲突日志文件。我读了很多关于这个文件的书，但对我来说还是有点神秘。以下是生成的日志文件中的相关“堆栈”版本：

Stack: [0x0000000033270000,0x0000000033370000],  sp=0x000000003336f8b0,  free space=1022k
Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code)
V  [jvm.dll+0x138998]
V  [jvm.dll+0x3f238a]
V  [jvm.dll+0x3efa30]
V  [jvm.dll+0x3ecfbe]
V  [jvm.dll+0x299f7a]
C  [msvcr100.dll+0x21d9f]
C  [msvcr100.dll+0x21e3b]
C  [kernel32.dll+0x159ed]
C  [ntdll.dll+0x2c541]

正如您所看到的，至少在这个日志文件中，错误甚至不是从一些java代码开始的，而是从ntdll库开始的，在该库中，指令执行在jvm本身出现异常[编辑：或者相反？以ntdll结束]。我不想把它当作“好吧……我会重新安装JVM和windows，也许它会工作”（虽然我肯定会这么做），但是试着看看我能不能做些什么。一些已知的问题或可以应用的修复，而不是我所说的那些显而易见的问题或修复。问题是这个错误是在超过36小时后发生的，所以很难重现

我还需要说我正在调用

System.gc();

每隔大约8秒，以确保清除内存。如果这在任何方面都很重要的话\

我不使用任何图形库

我没有使用任何JNI代码

非常感谢您的阅读和帮助

这是不相关的，但您可能不需要告诉jvm您想运行GC。@DaveNewton是的，您是对的，jvm通常在GC方面做得很好，但我注意到，由于调用和终止了大量线程，每隔几秒钟运行GC就会清除大量的垃圾堆积。它大大降低了内存使用率（通过查看windows任务管理器的“内存使用率”选项卡可以清楚地看到）。感谢您的输入。JVM将根据需要减少自己的内存使用。您还依赖于JVM实现（当然，当您要求它运行GC时，会有几个运行GC），但不能保证总是这样。如果你需要记忆，你需要记忆。我明白了。我会再测试一次，这可能是个错误。我会确保您拥有最新的JVM和windows更新。
