【问题描述】：
据我所知，我有一台服务器在请求期间传输数据期间抛出 System.OutOfMemoryException。从这个痕迹来看，我的假设是对的吗？
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

我的配置文件中的 maxArrayLength 和 maxStringContentLength 设置得非常高。是否有可能其中一个非常巨大，并导致通道抛出此错误？这是一个 .NET WCF 服务，通过 IPC 与另一个进程进行本地通信。
【问题讨论】：
-
really high是什么，你知道有一个最大限制。 -
您发送的有效负载有多大？
-
这是零星的还是特定消息导致的？
-
我正在发送基于员工浏览的报告摘要，因此这取决于组织有多少员工。摘要包含作为通用 Hashset 访问的页面的 url，这就是我想到 maxArrayLength 和 maxStringContentLength 的原因。使用查询字符串，哈希集可以多次包含相同的页面，只是具有不同的查询字符串值。但除此之外，我有点不知所措。这个特定的客户很大，所以我不会怀疑摘要是否大于 50MB。

@Conrad 它是零星的，甚至有时它似乎在跟踪的早期被抛出（我最早看到它被抛出的是 ServerFramingDuplexSessionChannel.OnOpen）
