What are your server specs? That is the number 1 reason people have office suite trouble. It is quite demanding.
@jensottos your device is not powerful enough to handle the office suite. 4gb ram is the minimum for it to to do anything, which is why it performs very poorly. Makes sense it would cut out as load on your odroid ram and cpu increases. Bummer, but also the truth. You’ll want to run it on a VPS or other server if you want proper performance and availability.
