IIS error: java.net.socketException:connection reset by peer

Problem:

Sometimes while calling WCF (.NET WCF or BizTalk schema/orchestration exposed as WCF service) service with hudge / large receives below error.

"java.net.socketException:connection reset by peer:socket write error"

It usually happens when sending attachment (base64 format) with SOAP request.

Root Cause :

Web-service which is hosted on Web-Server (IIS) couldn't handle large message.

Solution:

Need to configure the HTTP Runtime to accept large messages

1. Go to IIS
2. Open the web.config or corresponding web-service.
3. Put below entries.

<system.web>

     <httpRuntime maxRequestLength="2097151" />

</system.web>

Note: maxRequestLength value should be as per your need and below the max limit.
