From the rest of your mail, this clearly means the CURL/PHP extension.

This mailing list is for the libcurl library though, and usually you won't
find the best experts on the particular language bindings here. There's a
curl-and-php mailing list for CURL/PHP specific stuff.

This said, CURL/PHP of course uses libcurl so your issue can indeed be a
libcurl problem. You didn't tell us which libcurl version you're using and you
didn't tell us on which operating system you run it.

"Just stops" is not crashing in my terminology. But more importantly, is "X
minutes" the trigger for it to happen and if so, what is X? or is it when your
host get a renewed lease from the DHCP server or ...

You mean the browser that loads the HTML that your CURL/PHP using program
outputs?

Restart what? Isn't the CURL/PHP-using program (re-)started every time you go
to that web page?

What's the difference in your system after an hour that would make it
magically work again?

Wow, that seems really strange.
