Does FreeMiNT have a track record of a fine socket/network layer

I'm not absolutly sure what you mean, but if you wan't to know if other
network apps work correctly, yes they do. Including curl command line client
... and curl is using nothing but libcurl to do its job, so clearly libcurl
works (sometimes).
It does sound odd, and I'm sorry to say that I mostly suspect the
OS/network layer to not be fully socket compatible to the extent that
libcurl uses but that's just an early guess.
As I saw the TCP log I was thinking the same for the first moment, but
then why:
- does the error just trigger by an chance of 70%, not always?
Well, many bugs are hard to explain before the reason is found. I would expect
due to timing or by pure chance.
- does not trigger with my hardware, but with 2-3 different hardware setups.
And you have otherwise identical drivers used, OS revisions, libcurl version
and your app version?
Anyway, even if they are, I don't see how that necessary says that the bug is
in libcurl and not in any of the other parts! ;-) Although I of course don't
rule out any libcurl bugs. We fix more than one every week so I'm painfully
aware of their existance!
- What is libcurl doing that could not be supported that good by the OS?
I have no idea. But libcurl works rather fine on quite a lot of platforms so
when something simple (assuming it is) breaks on a rather esoteric platform my
gut reaction is to suspect the area I'm not sure is that proven. But as I
said, it was only a guess and should not be taken very seriously until we have
a lot more data and knowledge.
So my hope was that someone could tell me what this expire cleared message
means...
It means Curl_expire() was called with a zero argument to cancel the current
timeout. It is perfectly normal and expected and happens in lots of
situations. I don't think that's a very useful point to start digging on this.
I think the main focus now has to be to get someone who's able to do some
actual debugging (or printf sprinkling at least) to be able to repeat the
problem.
