Patrick,
I spent some more time on this, and now I believe that the problem is
not with the adaptor, but with Apache. After some timeout it just
cuts the socket. Possibly this is on purpose.... time to dive into
Apache docs :-(
cheers

Robert,
Thanks for the suggestion.
The problem is neither with curl nor with the DA. I tested this
excessively. It is something in the middle that breaks (WO adaptor
perhaps)... but I am really tapping in the dark...

I agree. I would suspect that a timeout is occurring in the
woadaptor, and presumably the woadaptor is not using the configured
timeout values. Georg, can you record and analyse the tcp i/o by
doing something like
# /usr/local/bin/tcpflow -i lo0 port 2004
on the machine running the application?
So why might the woadaptor be ignoring timeout settings, or doing
something else unexpected? I had thought about the connect timeout
rather than the response timeout; if there were other other
requests for which it takes many seconds to generate a response,
then the woadaptor might return early; but then it would generate a
"no instance available" page.
I had also thought that perhaps the response the application
generates could be malformed, from the point of view of the
adaptor; perhaps the content-length header is missing or
incorrect. That would explain why the problem doesn't show up with
direct connect, but doesn't explain why it's an intermittent
problem via the woadaptor.
