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 brakes (WO adaptor
perhaps)... but I am really tapping in the dark...
cheers

Have you checked to see if curl is resubmitting the request in case
it doesn't receive a response quickly? It seems like I had a
similar issue at one point with an application. Luckily for me I
didn't really need the response from DA so I just did my long
processing in a thread. The DA would then respond immediately to
curl. I was also generating a PDF in this process, but I was
sending the PDF to a list of email addresses once generated by the
thread.
If this is the case, I'm not sure how you need to solve your issue
since you need the DAs response. I do know that DAs that take a
while to process can cause strange behavior like you are describing
here.

Folks,
we have an app that produces bunch of PDF reports. There is a DA
that triggers this procedure, and when finished, this DA returns
an XML based status document (all this is part of a larger
workflow system without any end-user UI). This DA is called by a
curl from a script, and we have many similar WO apps and DAs.
For this particular DA, when the app is called as configured by
the Monitor (e.g. http://myhost/cgi-bin/WebObjects/MyApp/wa/blah)
from time to time we are getting an empty reply, e.g.
"curl: (52) Empty reply from server"
This is despite the fact that all PDFs are generated correctly and
the response XML is generated!
If we connect directly to the application (e.g. http://myhost:2004/
cgi-bin/WebObjects/MyApp/wa/blah) everything works fine.
I played with adaptor timeouts, but this did not change anything.
Any idea what could be causing this strange behavior?
Our system: Mac OSX Server 10.4.3 / WO 5.3
TIA
