[2020] Repeating error in private server console

Hey @Falcon4287

Welcome to our community.
Since you’re in a private server, do you have any mods installed?

Although this is an error that can rarely happen in vanilla servers, it does only happen once and in very rare situations. Since you mention that it seems to trigger often and during extended periods of time, we imagine it might be caused by some mod misconfiguration. Usually we recommend to disable all mods then enable them one by one until the issue reoccurs, but given that this is probably a server that heavily depends on the code and assets some of those mods provide, it might be a bit more difficult to spot the culprit in your case in particular.
