Thread stuck at webservices call in Weblogic server

When we make a Web Services API call, sometimes we are not getting response back. Our thread is just waiting for a response and does not get an error back.
Time outs are specified in the web service request using "com.sun.xml.ws.request.timeout" parameter. But, time outs are not working in this scenario.
Environment details:
Application server: Weblogic
Operating System: Linux
Webservices: Metro

Does anyone have any idea about this issue?

Thanks in advance for your help.
