问题描述
我正在尝试通过 WCF 服务调用将大量数据保存到数据库中.我无法调用该服务.它抛出一个错误.
codeProxy.SaveCodes(requestHeader, code, Rawcodes);<块引用>

<块引用>问题
当您运行基于 .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，您会注意到一个抛出 System.InsufficientMemoryException 异常.那么你收到类似于以下内容的错误消息:无法分配一个字节的托管内存缓冲区.可用数量内存可能不足.
原因
问题 1 的原因
当应用程序尝试为大对象堆 (LOH) 中的大对象分配内存.这当以下条件为真时，会触发错误消息:堆不能提供足够的内存来满足 LOH 分配要求.并发垃圾收集同时进行时间.问题 2 的原因
出现这个问题是因为垃圾收集器堆平衡小对象分配不是在具有超过 8 个逻辑处理器.正因为如此，更多的垃圾当有一个集合时，会触发集合以保持堆平衡不同处理器的工作负载不平衡.因此，应用程序在垃圾收集上花费更多时间.

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.
