I have a REST Web Service made with Spring MVC 3.2.0 that calls others REST Web Services also with Spring MVC. I'm having the following exception:

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

    ... 42 more

It happens randomly and when I check the log on dummy-2 WS there is no trace of error.

What can be causing this error?

  • Sounds like something outside of your server that cuts off the connection... But hard to tell without the know of what exactly are you trying to do. What does work, what have you already tried and such. Some code could also be handy. Commented Nov 26, 2014 at 0:11
  • check this. In case this doesn't help do a network trace via wireshark (or something similar tool) Commented Nov 26, 2014 at 7:28
