Server just froze and needs to be "killed" for restart

Hello,

my server just froze with players online, but they cannot do anything. No action was registered, but the server does not crash. No RAM releated. Plenty of free RAM. I need kill the process manually because it does not even registering the commands in the console.

Ubuntu Server 20.04

Full log before the freeze: hastebin - tupefofere (gamearea.cz)

Can somebody check the log and tell me why that happened? I see only so much stuff about: Kinematic body only supports Speculative Continuous collision detection . Then some text that I never saw. 

Thank you.

Well, try to Unload all the plugins, and see if there's any difference

I've had this problem before. I removed discord extension, along with rustcord. completely everything that relates to discord extension. Havent had a froze since then.

I've used rustcord for many months without any issues just recently its causing issues for some odd reason. I've moved on using other alternative to webhook to capture chat logs.,etc.
