What exactly happens with the failing requests? And is there a threshold
somewhere when the errors start to occur?

A single application shouldn't mix curl_multi_perform() and
curl_multi_socket_action() in the same transfer loop. If you do your
application event-based, only the latter function should be used. Mixing will
probably cause unexpected behaviors.

Also, I don't quite understand what you're doing with the threads?

libcurl 7.38.0 is 25 releases old, I would recommend an upgrade.

c-ares 1.7.3 is over 7 years old, I would recommend an upgrade.
