This error is intermittent and comes during deployment.Once we get this error we have restart the server.
Can someone please tell what is the cause of this error?
we dont have any server with Ip '192.168.50.5' as mentioned in the error message.and what exactly is the server trying to download here?

Hi,
How are you trying to deploy your application on the Server...Using Admin Console...or Using any Script Like WLDeployer?
The issue seems to be related to Http protocol in port 80.
Are you sure that in your Production environment there is not firewall blocking issue...on port 80...?
Some firewall settings rejects any existing connection to be opened for a long time....If your application takes some time, then please check that the firewall doesn't disconnect the existing connection until the deployment time gets over.
<font color=red>Note: </font>Sometimes this kind of issue happens when we try to deploy our application on WebLogic Server...at that time based on the XSD informations available in our DeploymentDescriptors...the Server tries to download those DTDs from the mentioned URIs....
Example:
web.xml has some entries like:
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
In above case if the Firewall of our production environment Blocks any request to pass through Port 80 (default Http Port) then we get such exceptions.
