引起：java.net.SocketException：来自服务器的文件意外结束

I am getting the below error quite intermittently when i run the WS through SOAP UI. Sometimes it does not work and then it keeps working and then again sometimes it does not work. One other issue is the test web service works fine provided by client with no issues but moment we switch to the production one it gives issues. Googled and did some changes (timeout on HttpConfig , jetty maxIdleTime) but still cant make it work :( Any ideas how i can narrow down what the issue is ?I am getting the below error quite intermittent
