【问题描述】:
我正在尝试使用回调同时向多个客户端发送大小超过 25 MB 的数据。我已经使用 wsdualhttp 绑定实现了该服务。当服务尝试同时将数据发送到 3 个以上的客户端时,它会引发“System.OutofMemory”和“无法分配内存”异常。我已经为 serviceThrottling、maxItemsInObjectGraph 以及 maxBufferPoolSize 设置了相关值。另外,我不能使用流媒体。有没有办法做到这一点?

【问题讨论】:
-
服务器端还是客户端失败?可以分享一下绑定配置吗?
-
我已经编辑了你的标题。请参阅“Should questions include “tags” in their titles?”,其中的共识是“不,他们不应该”。
-
请发布您的配置文件。设置并发回调数限制是不是OK?
-
@rene: 我已经分享了配置文件。
-
@Jocke:我认为问题不在于并发呼叫的数量。
