I have a timeout issue with a long running web service, and I can't figure
out where
the timeout value is coming from. In the client I end up getting the
following exception:
The underlying connection was closed: An unexpected error occurred on a
receive.

If I run the both web service and the client on my local machine, it runs in
about
700 seconds without issue.
When I try to run using a web service on a different machine, I get the
exception above. I have
checked both the machine.config and the web.config on the web service
machine, and
can't find any timeout setting that would be causing this to happen.
This happens *every* time at about 600 seconds, so I suspect there is a
timeout value
somewhere that I should be setting. I've tried everything I can think of,
and executionTimeou t is
set in the web.config:
<httpRuntime executionTimeou t="900" />
This is of course more than the 600 seconds I am seeing when the timeout
happens (at
around 600 seconds).
I also compared my local machine.config and web.config with the remote ones,
but
they don't appear to have significant differences.
Can anyone help?
Thanks,

Maybe the Timeout in the IIS Server is different.
Also, you can set a client timeout in the webservice proxy class.
You can try to call the webservice asynchronously and see what happens.
Just a few tips.

Is there a way to specify the server timeout for IIS in an asp file rather

socket.setdefaulttimeout is useful, but not always effective.
I'm setting that to 15 seconds.
If the host end won't open the connection within 15 seconds,
urllib times out. But if the host end opens the connection,
then never sends anything, urllib waits for many minutes before
timing out. Any idea how to deal with this? And don't just
