SpringREST模板java.net.SocketException:服务器的文件意外结束

我有一个用SpringMVC3.2.0制作的RESTWeb服务，它也用SpringMVC调用其他RESTWeb服务。我有以下例外情况：

25-11-2014 17:49:42-ERROR-ajp-/172.23.111.22:8109-9-pe.com.dummy.BusinessDummyImpl- I/O error on POST request for "http://172.23.111.23/dummy-2/rest/method1":Unexpected end of file from server; nested exception is java.net.SocketException: Unexpected end of file from server

这是随机发生的，当我检查dummy-2ws上的日志时，没有错误的痕迹

什么原因会导致此错误？

听起来像是服务器外部的某种东西切断了连接。。。但是如果不知道你到底想做什么，很难说。什么有效，你已经尝试过什么等等。一些代码也可能很方便。检查。如果这无助于通过wireshark（或类似工具）进行网络跟踪
