Azure：连接尝试失败，因为连接方在一段时间后没有正确响应，或者建立的连接失败，因为连接的主机无法响应 [英] Azure: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

问题描述

问题：在调用抓取数据的方法时，间歇性地从服务结构应用程序接收以下异常来自CosmosDB。 CosmosDB客户端是一个单独的连接
模式作为直接和TCP。我在这个问题上阅读的所有文档都表明端口耗尽或防火墙问题，h 代码是能够成功调用数据库
并在大多数时间获取数据，因此它不是防火墙问题。我们偶尔也会遇到此异常   当
对系统负载非常小而不是处理高负载时，这让我认为端口耗尽也不是原因。

异常：

[{" assembly"：" System，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089"，" method"：" System.Net.Sockets.Socket.EndReceive"，" level"：0 ，"line"：0}，{" assembly"："System，
Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089"，" method"："System.Net.Sockets .NetworkStream.EndRead"，" level"：1，" line"：0}]，" outerId"：" 61492510"，" message"："连接
尝试失败b因为连接方在一段时间后没有正确响应，或者建立的连接失败，因为连接的主机未能响应"，"键入"："System.Net.Sockets.SocketException"，"id"：""" 60917758"}]

关于故障排除的后续步骤或原因是什么的任何想法？

Problem: Intermittently receiving the below exception from a service fabric application when calling a method to grab data from CosmosDB. The CosmosDB Client is a singleton with connection mode as direct and TCP. All the documentation I have read around this issue suggests either port exhaustion or a firewall issue, however the code is able to successfully call the database and get data most of the time so it isn't a firewall issue. We also get this exception occasionally when there is very little load on the system and not when it is processing a high load, which makes me think port exhaustion isn't the cause either.

Exception:

[{"assembly":"System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089","method":"System.Net.Sockets.Socket.EndReceive","level":0,"line":0},{"assembly":"System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089","method":"System.Net.Sockets.NetworkStream.EndRead","level":1,"line":0}],"outerId":"61492510","message":"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond","type":"System.Net.Sockets.SocketException","id":"60917758"}]

Any ideas on next steps for troubleshooting or what the cause is?
