Hi,
I am writing because of a particular problem I have with my server.
I've recently bought a server from an outside hosting - 5GB of RAM, 5x3,0GHz processor, 15 GB of SSD memory. Initially it worked just fine but about time we (5 players) headed out of Shire it started to lag horrendously. Since then, if two or more players are playing at the same time and at least one of them is actively exploring server tends to kick out players at random, despawn their mounts and stop generating chunks. I tried to make this situation better by buying the better outside hosting offer (this time with 7GB of ram and 7x3,0GHz processor), but it improved nothing. What's more, the server's status shows that we are not actually even close to its technical boundaries.
What can be the cause of this? Is it reparable?
[PS. Very rarely the server does even crash. This is the text of the report:
