IBM Websphere on Windows- OutOfMemoryError: Failed to create a thread
提问by Kishnan
I have a J2EE application running on an IBM Websphere Application Server on a Windows Operating System.
我有一个 J2EE 应用程序在 Windows 操作系统上的 IBM Websphere Application Server 上运行。
Occasionally I see an OutOfMemoryError Exception with the following information in the javacore file.
有时我会在 javacore 文件中看到 OutOfMemoryError 异常，其中包含以下信息。
1TISIGINFO Dump Event "systhrow" (00040000) Detail "java/lang/OutOfMemoryError":"Failed to create a thread: retVal -1073741830, errno 12" received
Java is run with the following configurations: -Xms512m -Xmx1350m -Xscmx50M
Java 使用以下配置运行：-Xms512m -Xmx1350m -Xscmx50M
Analyzing the javacore file, the number of threads are just 124. Analyzing the heap dump, the memory occupied by the heap is about 500Mb.
分析javacore文件，线程数只有124个。分析heap dump，heap占用的内存在500Mb左右。
Given the relatively normal number of threads and heap size a lot lower than the maximum, I am trying to figure out why I see this error?
鉴于相对正常的线程数和堆大小远低于最大值，我想弄清楚为什么我会看到这个错误？
I′m not sure if this helps, but here is the top section of the javacore file...
我不确定这是否有帮助，但这里是 javacore 文件的顶部......

It seems like you run out of native memory. See "Thanks for the memory".
看起来您的本机内存不足。请参阅“感谢您的回忆”。
Reduce the heap space to 1024m:
将堆空间减少到 1024m：
2CIUSERARG -Xms512m
2CIUSERARG -Xmx1350m
Do you still have this OutOfMemoryExceptions?
你还有这个 OutOfMemoryExceptions 吗？
