系统错误.代码:8. 没有足够的存储空间来处理此命令 [英] System Error. Code: 8. Not enough storage is available to process this command

问题描述

我们有一些 Win32 应用程序(在 Delphi 2006 中编码)，有时用户会收到一条错误消息说系统错误.代码:8.没有足够的存储空间来处理此命令.".

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.".

从堆栈跟踪看起来它总是在 CreateWnd 调用期间

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

我一直无法弄清楚导致这种情况的原因，因为这种情况很少发生，我没有担心过，但我想找出导致它的原因并希望纠正它...

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...

完整的堆栈跟踪

编辑 2: 更多信息... 今天遇到这种情况的客户已经安装了我的应用程序大约 4 个月，并且它每天在他的 PC 上运行 8 小时.该问题仅在今天出现并不断重新出现，即使他杀死了我的应用程序并重新启动它.他系统上的其他应用程序都没有表现异常.重新启动后，问题完全消失.这是否指向史蒂夫提到的堆短缺?

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?

编辑 3: 有趣的 msdn 博客文章 此处 和此处 关于桌面堆的主题.虽然我不确定这是否是问题的原因，但看起来很有可能.

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.

推荐答案

如果您的程序使用大量 Windows 资源，则可能是资源堆短缺.

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

可以增加一个注册表项以增加 XP 的堆大小.对于 Vista，Microsoft 已将默认值设置得更高.我建议将默认的 3072 更改为至少 8192.

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.

此信息记录在 MS 知识库(或搜索内存不足").可以在文章 KB184802 中找到有关参数值的其他详细信息.

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.

我建议您阅读知识库文章，但有关更改的基本信息是:

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

1. 运行注册表编辑器 (REGEDT32.EXE).

1. Run Registry Editor (REGEDT32.EXE).

从 HKEY_LOCAL_MACHINE 子树，转到以下键:

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

SystemCurrentControlSetControlSession ManagerSubSystem

双击屏幕右侧的键:

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

windows 

在弹出窗口中，您将看到一个很长的字段被选中.将光标移动到字符串的开头附近寻找这个(值可能会有所不同):

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

SharedSection 使用以下格式指定系统和桌面堆:SharedSection=xxxx,yyyy,zzz 其中 xxxx 定义系统范围的最大大小堆(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.

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.

仅将 yyyy 值更改为 8192(或更大)，然后按 OK.

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

退出注册表编辑器并重新启动 PC 以使更改生效.

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

祝你好运.
