Since I keep having problems with multithreaded rendering (vedere https://www.mail-archive.com/[email protected]/msg01565.html), I tried again the render farm locally with only the threads of my CPU (8/16); but it doesn't work for me. When I try to start the client CinGG instances, instead of: RenderFarmClientThread::run: Session finished I get: RenderFarmClient::main_loop:400: Address already in use I first tried from root with ports 401 - 416. Then from no-root with ports 1026 - 1041. The result is always the same. The steps I take: - Start CinGG and activate "use render farm" and then set the 15 clients as Localhost port 1026, ..., 1041. OK to activate. - I open a terminal and start the following script: for n in 'seq 1026 1041'; do /home/paz/Desktop/./CinGG-20210228-x86_64.AppImage -d $n done - I get the message reported before and the rendering does not work. (the same happens with CinGG compiled) Any advice?
