我正在使用通过WebLogic 10.3部署在HP服务器上的Java应用程序。
版本信息：
WebLogic Version 10.3
OS Version B.11.23
$ java -version
java version "1.6.0.03"
Java(TM) SE Runtime Environment (build 1.6.0.03-jinteg_05_feb_2009_11_19-b00)
Java HotSpot(TM) Server VM (build 11.0-b16-jre1.6.0.03-rc2, mixed mode)
我收到此java.lang.OutOfMemoryError并且weblogic托管服务器正在关闭。它总是在编译器线程上。错误消息说检查swap和MAXDSIZ。我看了两眼，他们似乎没问题（见下文）。我已经浏览了论坛，看了很多东西，但似乎没有一个完全适用。我已经改变了堆并上下堆叠而没有运气。另外，我很确定这是惠普应用程序的第一个1.6端口。

我得到了一个核心和一个hs.log文件。这个问题看起来很相似，但不是决议的父亲。
JVM errors after updating to Java 6 Update 14
我发布了日志文件。没有堆空间显示接近100％。我不习惯看这些，并希望有人可以帮我指导解决方案。我看到物理内存很低但不是100％。
#
# An unexpected error has been detected by Java Runtime Environment:
#
# java.lang.OutOfMemoryError: requested 32756 bytes for ChunkPool::allocate. Out of swap space?
Possible causes:
- not enough swap space left, or
- kernel parameter MAXDSIZ is very small.

# Internal Error (allocation.cpp:128), pid=11593, tid=9

为将来的搜索者更新此内容。解决方案是升级JDK。
总结一下，这是由于随机OOM JVM崩溃造成的。每HP：
http://docs.hp.com/en/JDKJRE60RN/jdk_rnotes_6.0.05.html
在JDK 6.0.03中，由于QXCR1000920722，Java程序偶尔会在C堆中遇到内存泄漏，从而导致内存不足错误。 HP建议您从JDK 6.0.03升级到JDK 6.0.04（或更高版本），以防止由于QXCR1000920722而导致可能的C堆内存泄漏。
谢谢大家。

Google对此提出了一系列回应。我开始阅读first one，虽然它的结论（减少堆）是合理的，但它并没有真正谈论根本原因。所以...
这来自本机代码，表示代码无法从C堆分配内存。这可能发生了几个原因，其中一个原因是虚拟内存空间真正用于操作，另一个原因是C堆碎片化。如果HP有pmap，那么这是第一个开始（或找到它的等效物并从那里开始）的地方。如果您看到分配块在一个完整的块中填充虚拟内存空间，那么解决方案很简单：减少堆。
但是，如果您看到分配块分散在整个虚拟内存空间中，那么您将需要进行更深入的挖掘。有时会发生这种情况，因为您拥有的Java对象无法回收本机资源。有时它会因为操作系统中的怪癖而发生（我看到Solaris与线程堆栈混淆）。

这个答案不正确 - 见评论！
我将离开答案，以便人们可以看到讨论。
所以你的内存不足了。编译JSP是一种记忆困难，所以你的容器选择那个爆炸点并不太令人惊讶。
可以采取一些措施来探索这个问题，但我通常会先尝试最简单的补救办法：我给程序留出更多的记忆。
此：
VM参数：jvm_args：-Xms256m -Xmx1024m -XX：PermSize = 128m -XX：MaxPermSize = 256m
表示您正在使用非常“标准”的内存配置运行。我会尝试增加其中一些数字。
有一个（shell或.bat）脚本来启动WebLogic;我忘记了它的名字或结构。但是如果你在其中挖掘，你会发现Java被调用了一组进一步定义的选项。您可以关闭服务器，备份此脚本文件并对其进行编辑以调整内存设置（-Xms等）并查看重新启动时的位置。

我刚刚遇到这个问题，显然可能来自多种原因：本机堆（C-Heap）耗尽，OS物理/虚拟内存耗尽，C-Heap /本机内存泄漏。
我发现以下文章有助于理解该问题： http://javaeesupportpatterns.blogspot.sg/2012/03/outofmemoryerror-out-of-swap-space.html
