Connection closed before all GET/POST done

[Todd C. <tc...@in...>]

Hi,

 

The scenario is to send a GET request for a page and then send 2 POST
requests per client IP. There are 9 concurrent clients running. What I
find is that not all the POST requests get send before the curl-loader
exits. While running the test, I capture the packets. From the trace, I
find that for some of the client(s), the TCP connection is closed before
the client is able to complete all the transactions. Please note that it
is always the client initiates the TCP connection close (send FIN
packet). I have the following questions:

 

1.	Why client closes the TCP connection before it completes all
transactions? Is there a way to tell the client not to close the TCP
connection until all transactions of the client is complete? 
2.	Is there a way to tell the client not to close the TCP
connection at all with a "timeout value"? This is because in my case the
server will initiate the close by sending the FIN packet. The purpose of
the "timeout value" is that the client can initiate the close connection
only after the timeout value passed.

 

Below is my curl-loader configuration:
