Prefetch request body failed for direct proxy for Apache mod_proxy HTTP server

I am using Apache HTTP Server mod_proxy as a proxy between my client and server. I can connect to my proxy server from my client. And then the client can establish a connection and send data to the server. But in the middle, somewhere the connection is lost, and it gives the following error:

(OS 10054)An existing connection was forcibly closed by the remote host.  : proxy: prefetch request body failed to 10.131.x.x:80 (10.131.x.x) from 10.131.y.y ()

I tried adding saved and other properties, but this did not solve my problem. Here are my changes to the httpd.config file:

<IfModule ssl_module>
    SSLRandomSeed startup builtin
    SSLRandomSeed connect builtin
    </IfModule>
    <IfModule mod_proxy.c>
    ProxyRequests On
    ProxyVia On
   </IfModule>

    <Proxy *>
        Order deny,allow
        Deny from all
        Allow from 10.131.x.x
    </Proxy>

The following variables are also added:

 KeepAlive On
 MaxKeepAliveRequests 0
 KeepAliveTimeout 15
 Listen 8080

Please know if anyone has encountered the same problem and resolved it.

Thanks, Arindam.
