The Classic Macs website download area was over 14,737 files and the previous download manager was choking on it. It would literally take 10 minutes just to scan for new files and it was leaving sql logs uncleared. I found another one that while maybe not as pretty it is MUCH faster and doesn't seem to have any issues with this many files.
You can view the new one here: macos.retro-os.live/index.php/new-downloads - please let me know if you have any comments!
