I have a problem with my Forge Server. The Problem was not there all the time. I think the Server devolved the Problem round about Version 1.16.1. But I’m not sure. The Problem is quite simple but the cause is...idk. The Problem is: That sometimes, it feels like a 50/50 chance, when a player logs into the server or is logging out, the server is crashing. You see in the logs that the server hang up and then considers himself to be crashed. That’s all I can see in the logs and that’s fucking confusing.
The Clients connecting are Forge Clients on the latest Version. We are using some Mods: DynMap, NetherPortalFix, oneplayersleeping, TorchMaster. And there was the mod simplefarming on the Server. The Problem was already there before i added the first four Mods and the server was already running without problem with simplefarming on it. So it has nothing to do with the Mods.

What are your thought guys? We think there is maybe a problem with Ubuntu and the Network handling. The Ubuntu version is 18.04.04.
