Question

IBM WebSphere因“java / lang / OutOfMemoryError本机内存耗尽”而失败，并生成javacore文件。但是这个文件不包括Native memory（NATIVEMEMINFO）部分。为什么？

IBM WebSphere Application Server 7.0.0.39

Answer 1

版本字符串显示您正在运行使用J9 VM2.4的早期IBM Java 6.0。

NATIVEMEMINFO部分是在使用J9 VM2.6的IBM Java 6的后续版本中引入的：

您使用的版本不会生成包含NATIVEMEMINFO部分的javacore文件。

Java Core不包含本机内存部分
