Hi Dave, Indeed after setting LP_DEBUG=fs I get a lot of repetitive printing during the interactive actions. After some more searching it finally seems that the problem is on our side, which forces some pipelines to be continuously re-created. Thanks everyone for your help, and I apologize for the confusion and the hassle. :/
