+1.. however I remember this was not so easy to catch in Windows evenjust before the 1.0 release time.. Eric, would be good if you could filea JIRA so that we could include a test for this with each release

I think we need to add text to the WARN implying this is business as usual too
e.g. "Probably caused by an HTTP Keep-alive session ending."

Oh Ok.
Yes, I am using Windows, and the sample stockquote client packaged in the
samples in the synapse dist.
I guess a WARN message should be appropriate in this case.

Are you using windows? Also whats your client application written in?
Most probably what happens is that your client sends the request stating
HTTP 1.1 which implies the use of keepalives unless a "Connection:
close" header is specified along with the request. But as soon as it
gets the response back - the client closes the connection and possibly
terminates itself. One way to find out if this is the cause is to send
the request to Synpase through TCPMon etc and check if what I am saying
is taking place - note that the sample stockquote client etc that uses
Axis2 in our samples also suffers from this - but this is not a defect
with Synapse. We could update Synapse to just do a WARN on this.. your
thoughts are welcome

Hi,

I checked out the latest sources from thr SNV trunk today - 8th Oct.

When running synapse sample 0 : with configuration :
<definitions xmlns="http://ws.apache.org/ns/synapse";>
    <!-- log all attributes of messages passing through -->
    <log level="full"/>
    <send/>
</definitions>

Although the sample client got back the response, I got the following at

the

server logs  :
