                 Key: AXIS2-5250
                 URL: https://issues.apache.org/jira/browse/AXIS2-5250
             Project: Axis2
          Issue Type: Bug
          Components: transports
    Affects Versions: 1.5.5
         Environment: Solaris, UNIX. Java
            Reporter: Rachna
            Priority: Blocker


The client stub was working perfectly fine with lower load/requests. The same 
application when went live failed, giving some successful responses and some " 
Timeout waiting for connection" exceptions with heavy load/requests.

The axis version used is axis2-1.5.5

Please find the exception below -

According to me, the above exception is taken care in the original base code 
generated with wsdl file. The code is pasted below which should take care the 
cleanup of the transport ( http sessions) but it is not as I am getting some 
"Timeout waiting for connection" exceptions.
finally {
                if (_messageContext.getTransportOut() != null) {
                      
_messageContext.getTransportOut().getSender().cleanup(_messageContext);
                }

Can you please suggest what is going wrong here. 
Let me know if more information is required.
