但是，如果您看到分配块分散在整个虚拟内存空间中，则需要进行更深入的挖掘。有时发生这种情况是因为您的Java对象没有回收本机资源。有时这是因为操作系统中的一个怪癖（我看到Solaris与线程堆栈混淆了）。这个答案是不正确的-请参阅注释 我把答案留给大家，这样大家就可以看到讨论了
所以你的内存不足了。编译JSP是一个占用内存的问题，所以容器选择了那个点进行扩展也就不足为奇了 可以做一些事情来探索这个问题，但我通常先尝试最简单的解决方法：给程序更多内存 这： VM参数：jvm_参数：-Xms256m-Xmx1024m-XX:PermSize=128m-XX:MaxPermSize=256m 表示您正在使用相当“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；我忘了它的名字或结构。但是如果你仔细研究一下，你会发现Java被调用时有一组选项，这些选项是进一步定义的。您可以关闭服务器，备份此脚本文件并对其进行编辑，以修改内存设置（-Xms等），然后查看重新启动时的情况
为将来的搜索者更新此内容。解决方案是升级JDK 总而言之，这是由于随机的OOM JVM崩溃造成的。每马力： 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QXCR1000920722可能导致的C堆内存泄漏
谢谢大家。我刚刚遇到了这个问题，它显然有多种原因：本机堆（C-Heap）耗尽、操作系统物理/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这个问题：
将所有计算机输出缩进四个空格，使其可读。谢谢。实际上，我对堆和烫发大小参数做了上下调整。目前，我得到的参数设置错误如下：-Xms256m-Xmx1024m-XX:PermSize=128m-XX:MaxPermSize=512m我也尝试过将它们设置为相同的值，包括较高和较低的值（-Xms1024m-Xmx1024m，-Xms512m-Xmx512m）。没有任何区别。根据日志条目，堆似乎正常。我想如果它是PermGen，它会抛出一个不同的错误，但我也尝试过更改它们。感谢您提供的有用信息。不幸的是，当这个创可贴修复失败时，我通常不得不打电话给部队（即某种支持，因为你支付的是商业操作系统）。我对HP-UX有强烈的反感：在我看来，HP构建了出色的硬件，但不应该尝试任何软件。我在最新版本的自述文件中发现了这一点：在JDK 6.0.03中，Java程序偶尔会因QXCR1000920722而在C堆中出现内存泄漏，从而导致内存不足错误。基于上面的评论，这听起来很有希望。Carl，您建议增加堆和永久空间并不是OP问题的正确答案，该问题是“交换空间不足”。事实上，这个错误通常是通过降低堆和/或permgen来解决的，以便减少对所使用的总地址空间的压力。对于所使用的本机空间，通常还有其他一些根本原因（可能是驱动程序中的一个大问题，或者是一些工具，或者JVM，正如上面其他人所断言的那样）。但是盲目地增加堆/永久性恐怕不是解决这个问题的办法。@charlie arehart:谢谢你的提醒！拜你的智慧所赐，我正在编辑这个答案以表明它是错误的。我会删除，但是人们会丢失你和marta的评论。我在我的服务器上没有看到pmap的man条目，我会看到我可以找到的等效条目。这次崩盘并非在任何可预测的时间发生，尽管它确实每天至少发生一次，有时两次。我正在考虑尝试一个新版本的HP JDK，看看这是否会有所不同？堆
