未能分配的134217728个字节的托管内存缓冲区。可用存储器的量可以低 [英] Failed to allocate a managed memory buffer of 134217728 bytes. The amount of available memory may be low
问题描述
我想通过WCF服务调用保存庞大的数据资料库。我不能调用服务。它抛出一个错误。
codeProxy.Save codeS（requestHeader，codeS，原codeS）;
未能分配的134217728个字节的托管内存缓冲区。该 可用内存量可能不足

问题
当您正在运行的.NET Framework 2.0的应用程序时， 应用程序崩溃。如果您调试应用程序，您会发现一个 System.InsufficientMemoryException异常。然后你 收到类似于以下错误消息：无法 分配字节的托管内存缓冲区。可用的量 内存可能不足。
原因
第1期的原因
出现此问题的间歇性，当应用程序试图 在一个大对象堆（LOH）的大型对象分配内存。该 错误信息被触发当满足下列条件为真： 堆不能提供足够的存储器来满足蕙分配 请求。一个并发垃圾回收过程中同 时间。问题2的原因
出现此问题的原因垃圾回收堆平衡为小 对象分配不具有的计算机上进行努力 超过8个逻辑处理器。正因为如此，更垃圾 集合触发堆保持平衡时，有一个 不平衡的工作量不同的处理器。因此，该 应用程序花费在垃圾收集更多的时间。

Issue
When you are running a .NET Framework 2.0-based application, the application crashes. If you debug the application, you notice that a System.InsufficientMemoryException exception is thrown. Then, you receive an error message that resembles the following: Failed to allocate a managed memory buffer of bytes. The amount of available memory may be low.
CAUSE
Cause of Issue 1
This issue occurs intermittently when the application tries to allocate memory for a large object in a large object heap (LOH). The error message is triggered when the following conditions are true: The heap cannot provide sufficient memory to satisfy the LOH allocation request. A concurrent garbage collection is in progress at the same time. Cause of Issue 2
This issue occurs because garbage collector heap balancing for small object allocations is not performed diligently on computers that have more than 8 logical processors. Because of this, more garbage collections are triggered to maintain heap balancing when there is an unbalanced workload in different processors. Therefore, the application spends more time on garbage collection.
