Problem Description: Error: "-27780: read to host failed: [10054] Connection reset by peer"
The user gets the following error messages during replay of a Web script:
"Error -27780: read to host <host name> failed: [10054] Connection reset by peer"
"Error -27790: Failed to read data from server <host name>"
Diagnosis:
The client sends a POST request to the server and gets a response with HTTP status 200, connection close and redirection using both JS code and meta-refresh. There is no content-length, so the client is supposed to decide when to close the connection. Internet Explorer closes the connection before sending the request to the redirection URL. But, LoadRunner does not; later the server closes the connection, and the result is the error message.
原因可能是多方面的，不过更常见的原因是：
①：服务器的并发连接数超过了其承载量，服务器会将其中一些连接Down掉；
②：客户关掉了浏览器，而服务器还在给客户端发送数据；
③：浏览器端按了Stop 。
--------- Troubleshooting-----------------------------------
Use web_set_sockets_option ("CLOSE_KEEPALIVE_CONNECTIONS", "1")
Add the following step after the POST step:
web_set_sockets_option("CLOSE_KEEPALIVE_CONNECTIONS", "1");
This step closes all the open connections, and as a result, LoadRunner stops waiting for the rest of the response of the redirection.
--------- 经验-----------------------------------
先排除：
1、程序问题
2、服务器防火墙、杀毒软件问题
3、使用IP 欺骗无效。
结论：打开socket后记得关
