Hi all,

We have a cxfbc:provider where the web service is in another external server. When we invoke too many threads, some of these generate the following error:

2013-07-11 08:30:15,436 ERROR Servlet.service() for servlet AxisServlet threw exception

We thought that the problem was a timeout but we have set the following configuration:

     <http-conf:conduit

          name="servicePort.http-conduit">

          <!-- deactivate HTTPS url hostname verification (localhost, etc) -->

          <!-- WARNING ! disableCNcheck=true should NOT be used in production -->

          <!--  <http-conf:tlsClientParameters disableCNcheck="true" />  -->

          <http-conf:client ConnectionTimeout="1080000000" ReceiveTimeout="1080000000" />

     </http-conf:conduit>

but the problem is kept,  any idea?

Thanks!
