Well, a single fetch seems to be taking almost 3 minutes, and you have
configured Smokeping to fetch the page 20 times every 5 minutes. So the
Curl probe never gets finished and is killed when the timeout occurs.
The solution would be to increase the 'step' parameter and/or decrease
the 'pings' parameter. Note that with Smokeping 1.36 you can do this
for just the Curl probe while keeping the parameters for the rest of
the probes (if you're running any).
(It would be nice if the probe could signal back the number of
succesful pings when it's killed by the timeout code, but at the moment
it doesn't. In your case you would still get constant 95% loss.)
