It does feel like the server is struggling since webUI is also having trouble loading debug sample artifacts during the upload. But I'm not sure why that would be the case. The client console is hanging after "uploading dataset changes" and I can see the fileserver.py process putting load on the server cpu but don't see any files being added or changed on the local fileserver folder. Is there a way to check what is the fileserver doing? I don't see anything suspicious in log.
