Question

遇到以下错误： “异常：从线程”Thread-8“中的UncaughtExceptionHandler抛出java.lang.OutOfMemoryError。

以下是生成的日志文件中的GC堆历史记录。（显然不是完整的日志文件。）它似乎通过“edan space”表示使用率是100％，但我不确定这个信息是否告诉我。

虚拟机是否空间不足？
GC是否无法清理它，或者没有任何东西可以自由清除它真的用完了内存吗？
将简单地使用命令行参数来增加内存
解决这个问题？

某处是否有泄漏？

Answer 1

GC调用后的堆= 11026（完整619）：

GC调用后的堆= 11027（完整620）：    ParOldGen
   对象空间699392K，99％使用

可以从中推断出，在日志结束时，您只能看到完整的GC，并且在 GC之后老一代已经完整。因此，您的应用程序内存不足或泄漏。

OutOfMemory：这个日志文件实际告诉我什么？
