系统错误。代码：8.没有足够的存储来处理这个命令 [英] System Error. Code: 8. Not enough storage is available to process this command

问题描述

我们有几个Win32应用程序（在Delphi 2006中编码），其中有时用户会收到一条错误消息，说系统错误。代码：8.没有足够的存储可用于处理此命令。

从stacktrace看起来它总是在CreateWnd调用

我从来没有能够去导致这种情况的底部，因为它发生很少很少我没有关心，但我想知道是什么原因，并希望纠正它...

编辑：完全堆栈跟踪

编辑2：更多信息...今天体验过的客户我的应用程序安装了大约4个月，每天8小时运行在他的电脑上。这个问题今天才出现，即使他杀了我的应用程序并重新启动也不断重现。他的系统上的其他应用程序都不奇怪。重新启动后，问题彻底消失。这是否指向史蒂夫提到的堆不足？

编辑3：有趣的msdn博客文章这里和这里。虽然我不知道这是否是问题的原因，但它肯定是可能的。

解决方案

如果您的程序使用了很多的Windows资源可能是资源堆缺乏。

有一个注册表项可以增加，以提高XP的堆大小。对于Vista，Microsoft已经将默认值设置为较高。我建议将默认3072更改为至少8192。

此信息记录在 MS知识库（或搜索内存不足）。有关参数值的其他详细信息，请参见文章 KB184802 。

我建议你阅读知识库文章，但更改的基本信息是：

1. 运行注册表编辑器（REGEDT32.EXE）。




2. 从HKEY_ LOCAL_MACHINE子树中，转到以下项：

     \System\CurrentControlSet\Control\Session Manager\SubSystem 
     




3. 在屏幕的右侧，双击该键：

     windows 
     




4. 在弹出窗口中，您将看到一个非常长的字段。将光标移动到字符串开始处，寻找这个值（值可能会有所不同）：

     SharedSection = 1024,3072,512 
     




5. SharedSection使用以下格式指定系统和桌面堆： SharedSection = xxxx，yyyy，zzz 其中 xxxx 定义全系统堆的最大大小（以千字节为单位）， yyyy 定义每个桌面堆的大小， zzz 定义非交互式窗口站的桌面堆大小。 p>




6. 仅将 yyyy 值更改为8192（或更大），然后按OK。




7. 退出注册表编辑器并重新启动PC，使更改生效。

祝你好运。

We have a few Win32 applications (coded in Delphi 2006) where sometimes the user gets an error message saying "System Error. Code: 8. Not enough storage is available to process this command.".

From the stacktrace it looks like it is always during CreateWnd call

I've never been able to get to the bottom of what causes this and as it happens fairly seldom I haven't been to concerned, but I would like to find out what causes it and hopefully rectify it...

EDIT: Full Stacktrace

EDIT 2: More info... The client who experienced this today has had my app installed for about 4 months and it is running on his PC 8 hours a day. The problem only appeared today and kept reappearing even though he killed my app and restarted it. None of the other apps on his system behaved strangely. After a reboot the problem goes away completely. Does this point towards the heap shortage that Steve mentions?

EDIT 3: Interesting msdn blog post here and here on the topic of the desktop heap. Though I'm not sure whether this is the cause of the problem it certainly looks likely.

解决方案

If your program uses a lot of windows resources it could be a Resource Heap shortage.

There is a registry entry that can be increased to raise the heap size for XP. For Vista Microsoft already sets the default value higher. I recommend changing the default 3072 to at least 8192.

This information is documented in the MS Knowledge Base (or search for "Out of Memory"). Additional details concerning the parameter values may be found in article KB184802.

I suggest you read the knowledgebase article but the basic info on the change is:

1. Run Registry Editor (REGEDT32.EXE).

2. From the HKEY_ LOCAL_MACHINE subtree, go to the following key:

   \System\CurrentControlSet\Control\Session Manager\SubSystem
   

3. On the right hand side of the screen double-click on the key:

   windows 
   

4. On the pop-up window you will see a very long field selected. Move the cursor near the beginning of the string looking for this (values may vary):

   SharedSection=1024,3072,512
   

5. SharedSection specifies the System and desktop heaps using the following format: SharedSection=xxxx,yyyy,zzz where xxxx defines the maximum size of the system-wide heap (in kilobytes), yyyy defines the size of the per desktop heap, and zzz defines the size of the desktop heap for a "non-interactive" window station.

6. Change ONLY the yyyy value to 8192 (or larger) and press OK.

7. Exit the Registry Editor and reboot the PC for the change to take effect.

Good luck.
