线上web程序运行一段时间后会频繁抛出如下异常，回收iis应用池则正常。过段时间继续出现此异常，回收后则正常，然后如此循环。异常信息如下 ：

An error occurred while making the HTTP request to https://xxx.cn/Services/Service.svc. This could be due to the fact that the server certificate is not configured properly with HTTP.SYS in the HTTPS case. This could also be caused by a mismatch of the security binding between the client and the server.

通过wcf trace，得到异常日志，分析得到message为An existing connection was forcibly closed by the remote host.

System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size)
System.Net.FixedSizeReader.ReadPacket(Byte[] buffer, Int32 offset, Int32 count)
System.Net.Security.SslState.StartReceiveBlob(Byte[] buffer, AsyncProtocolRequest asyncRequest)
System.Net.Security.SslState.StartSendBlob(Byte[] incoming, Int32 count, AsyncProtocolRequest asyncRequest)
System.Net.Security.SslState.ForceAuthentication(Boolean receiveFirst, Byte[] buffer, AsyncProtocolRequest asyncRequest)

服务通过https通信 ，请教该如何排查问题所在？
