Doesn't matter anymore. I think I found the issue. Failed handles do not increment `received` but before resending them I kept checking if there are any empty slots for the transfers. So when all failed (Im not yet sure if cumulatively or at the same time), they could not be readded anymore.Thank you for your help!Temat: Re: Curl Multi with easy handle timeoutData: 2023-04-28 22:27Nadawca: "herhor67 via curl-library" <curl-library@lists.haxx.se>Adresat: "Daniel Stenberg" <dan...@haxx.se>; DW: "herhor67" <herho...@interia.pl>; "herhor67 via curl-library" <curl-library@lists.haxx.se>; I will post a thinned out part of the code in an attachment - hopefully it will be available. If this is not too much to ask - I would be greatly grateful :) Its purpose is to run N connections every second - the external API is rate-limited. From what I've seen, usually my counter `(sent-received)` is either equal or very close to `still_alive`. However, on rare occasions, my counter maxes out (equal to `MAX_CONN`) and LibCURL reports 0 running handles. Then it stays like that indefinitely.
