Pushing the Raspberry Pi 400 to the Limit

Recently tried to run 3 programs from a Raspberry Pi 400. The two services ran just fine without any issues. I did a clean install of Ubuntu Lunar Lobster 23.04 and installed Navidrome alongside Jellyfin. The Pi handles it like a champ, 2 continuous streams from Jellyfin are no problem. The only issue I ran into was crashing when I installed NextCloud onto the Pi. At that point, I saw performance issues and crashing. Anyone else try to do something crazy? I disabled NextCloud and seem to have returned to normal. I have some lean for you...
