Actually, sorry, it's red hat 7 we're using (because a customer requires
it)

Hi,

We're building the same kind of application with libcurl under linux
too. In
fact this application has already a version using curl (spawn a new
process
execing curl executable) that we used a lot and worked fine.
Of course the point now is to use libcurl "internally". The code is
"beta"
and I'll do asap some stress test of this new version but as far as I
tried
for the moment I didnt experience the same kind of problems.
I'm under redhat 9 or fedora core 1, curl 7.12+, c-ares, openssl 0.9.7d.

I would suspect that your linux box is not properly configured at the
network level.

1) If you want I will let you know as soon as I run some stress test
using
libcurl if I have the same problems.

2) We may encounter the same kind of problems, I will be interested by
sharing any issues you or us may encounter related to the use of libcurl
(not only because of libcurl I mean :) )

3) Try to give here more information. Did you try manually the curl
command
line version (you can have information on timings as well with the right
options) and check the results ?
Example :
curl
-w"\n%{time_namelookup}|%{time_connect}|%{time_total}|%{http_code}\n" -
-connect-timeout 30 -m 120 ... filename
