StatikI don't know if it's logs.tf or the curl extension but the uploads fail to often, i'd say 50% of the times and i've read curl has lots of bugs.
I have been using it for a long time without problems. Can you be more specific about the error? It logs upload errors to the SourceMod error logs, so you should be able to find them there.
StatikIs there a public repository of your plugins where a can make pull requests? I would love to see your plugin working with SteamTools instead of cURL.
Unfortunately the sources are only available in a zip file. I am using a private TFS repository as source control. However, I have seen other problems with cURL, so I would definitely like to have support for SteamTools. If you want to implement it, I would very much welcome that! Make SteamTools the default way of communication. Test it thoroughly, and send the source to me. :) You might want to add me on Steam for any clarifications.
