          Issue Type: Bug
    Affects Versions: 1.1.1
         Environment: Os: AIX 5.3 TL5 SP1

As discussed on the mailing list with subject [Synapse 1.1.1] - Proxy timeout 
(vendredi 13 juin 2008 17:42 Paris):

I encounter some timeout problems with a Synapse installation. My 
client(170.217.170.36) invokes Synapse(170.243.1.100:8210), then Synapse do its 
job. But before it can respond to my client, it says " HTTP connection 
[/170.217.170.36:2115]: Timeout". My client never receives the response.

Previously, it took 60 seconds to have a timeout.
I tried to increase the timeout with nhttp.properties.

But... It seems that my Synapse locks between the moment it prepare the 
connection (I see HTTP connection [/170.217.170.36:3520]: HTTP/1.1 200 OK) and 
the moment it sends the response data.

contentType from the OMOutputFormat =text/xml 2008-06-13 17:33:49,887 
[HttpClientWorker-2] DEBUG SOAPMessageFormatter - contentType returned

2008-06-13 17:36:45,046 [I/O dispatcher 4] DEBUG ServerHandler - Connection

- HTTP connection [closed]: Closed
2008-06-13 17:36:45,046 [I/O dispatcher 4] DEBUG ServerHandler - Connection 
closed

After this, it seems that Synapse is locked. "CTRL+C" can't close the 
instance....

The Synapse job is to transform the reveived message into an XMLMessage called 
AGORAMessage.
Then, this message is sent to an endpoint (stj2ee).
The response of this endpoint is then transformed again from AGORAMessage into 
a SOAP message.
This SOAP message should be returned to the client. (Line 74 in the synapse.xml)
