Axis2 Timeout waiting for connection

My code is consistently generating the following error:

org.apache.axis2.AxisFault: Timeout waiting for connection
    at org.apache.axis2.AxisFault.makeFault(AxisFault.java:430)
    at org.apache.axis2.transport.http.HTTPSender.sendViaPost(HTTPSender.java:203)

After extensive searching the solution appears to be here:

Except I cannot access http client directly (that is done in auto generated code).

Instead I have tried:

http://wik开发者_开发百科i.apache.org/ws/FrontPage/Axis/AxisCommonsHTTP

Which seems to help slightly. However it only delays the problem I always get the timeout. Also the instructions appear to be for an old version of Axis since Axis2 does not have AxisProperties. I am using version 1.5.1. Any suggestions?

I think this was a bug, see here and has been fixed with Axis2 1.5.2 (at least for generated code). With custom code, you need to tackle this problem manually.
