这条消息似乎没有多久 - 我最后只附上了一份冗长的日志报告
大家好，
我正在运行一个用Java实现的实验性爬虫。 最近，在运行36小时后，JVM崩溃，发出异常访问冲突日志文件。我读了很多关于这个文件的内容，但对我来说仍然有些神秘。这是相关的＆＃34; Stack＆＃34;生成的日志文件中的版本：
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]
正如你所看到的，至少从这个日志文件中，错误甚至没有从一些java代码开始，而是使用ntdll库，其中指令执行在jvm本身达到异常[编辑：或者也许另一种方式？以ntdll结尾？]。我不想要将其视为＆＃34;嗯......我将重新安装JVM和Windows，也许它会工作＆＃34; （尽管我确实这样做了），但试着看看我能做些什么呢。可以应用的一些已知问题或修复，除了我所陈述的明显问题。问题是这个错误在超过36小时后发生，因此很难再现。
另外我需要说我正在调用
System.gc();
每隔约8秒钟确保清除内存。无论如何这都很重要。\
我不使用任何图形库。
我不使用任何JNI代码。
非常感谢阅读和可能的帮助，
阿米尔。
附加 - 几乎完整的日志文件（hs_err_pid10544.log），没有非常冗长的线程详细信息：
