Hi Juggernaut
The allocations are already higher than the default settings.
Settings_ChunkLifeSpan=2400
Database_InMemory=True
Plugins_Memory=16384
The players are connecting (that's what happens up to 10%) but are not being authenticated. This does not happen all the time, it can happen a couple of times a day, or be fine for days on end.
The server resouces are at 1% CPU and 8% RAM. I don't think resources are an issue
