有50％的可用内存时系统内存不足异常?！

问题描述

我正在使用共享类(如下面所示)或作为实体POCO对象将某些表缓存到内存中.我都尝试过.

公共共享函数CacheDT()作为cacheDS.CacheDataTable
        如果_CacheDT什么都没有，则
            将myCacheTableAdapter调暗为新的cacheDSTableAdapters.CacheTableAdapter
            _CacheDT = myCacheTableAdapter.GetData()
        万一
        返回_CacheDT
    结束功能

在我的数据库中有很多不经常更改的表.这就是为什么我要在内存中缓存大约2 GB的数据.我的开发人员计算机的RAM为16 GB，Web服务器的RAM为64 GB.我正在系统内存不足异常正常 内存使用量甚至达不到8 GB.我发现有一篇很好的文章向我解释了这与物理内存无关，只是解决了事实

在文章中，他说这对64位计算机应该不是问题，但是我的两台计算机都是64位.它是怎么发生的?如何通过在VB或C#中设置内容或对代码进行编码来管理内存?

当我禁用名为启用Visual Studio托管过程"的选项时，它开始更频繁地发生.可能与此有关吗?

感谢您的建议.

解决方案

Hi,

I am caching some of my tables into memory using shared class like show below or as entity POCO object. I tried both of them.

    Public Shared Function CacheDT() As cacheDS.CacheDataTable
        If _CacheDT Is Nothing Then
            Dim myCacheTableAdapter As New cacheDSTableAdapters.CacheTableAdapter
            _CacheDT = myCacheTableAdapter.GetData()
        End If
        Return _CacheDT
    End Function

there are plenty of tables which arent changed frequently in my DB. that's why i am caching about 2 GB of data in the memory. my developer machine has 16 gb ram and webserver has 64 gb ram. I am getting system out of memory exception altougt physical memory usage isnt even reaching 8 gb. I found that nice article explaining me it is nothing to do with physical memory but addressing fact http://blogs.msdn.com/b/ericlippert/archive/2009/06/08/out-of-memory-does-not-refer-to-physical-memory.aspx

Indeed in the article he says it shouldnt be a problem with 64bit machine but my both machines are 64. how does it occur? how can I manage my memory by setting up something or coding something in VB or C#? 

EDIT: It started happening more often when I disabled option called "Enable the Visual Studio hosting process". can it be something related to that?

thanks for suggestion.
