Description

Synapse configuration:

<definitions xmlns="http://ws.apache.org/ns/synapse">

<in>
<log level="full"/>

<send>
<endpoint>
<wsdl uri="http://hostname:2006/echo/echo.wsdl" service="EchoService" port="EchoPort">

<suspendDurationOnFailure>5</suspendDurationOnFailure>
<timeout>
<duration>3</duration>
<action>fault</action>
</timeout>

</wsdl>
</endpoint>
</send>

</in>
<out>
<send/>
</out>
</definitions>

When simple 'echo' endpoint is deployed and working - everything is OK.
But when I undeploy it and ask Synapse, I've got series of exception:

First query:

End every next query ends with this exception.
Even if I redeploy echo endpoint, Synapse does not process my requests and responses with 0 bytes:

Mon Nov 05 10:13:59 CET 2007:INFO:Got response for [EchoBinding.echo:Request 1] in 18ms (0 bytes)

And after a few seconds in logs I have:

2007-11-05 10:19:06,408 [ CUT ] [Timer-0] INFO LogMediator To: /soap, WSAction: , SOAPAction: , Direction: request, Envelope: <?xml version='1.0' encoding='utf-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:echo="http://www.springframework.org/spring-ws/samples/echo"><soapenv:Body>
<echo:echoRequest>dupa123</echo:echoRequest>
</soapenv:Body></soapenv:Envelope>

After restarting Synapse everything backs to normal - so it isn't endpoint's issue.
