It turns out that the SoapClient is sending data on a half-closed connection. The server had earlier sent a FIN packet, that had been ACKnowledged by the client.
Now, from a TCP point of view, it is permissible to send data with of before your own FINish.
But POSTing something to which you're expecting a reply, on a half-closed connection?
