Minecraft server freezing every 1-2 days

[TheDutchMC04]

I've been having issues with my servers just freezing (talking VelocityProxy and Minecraft (Paper)). I think that this is due to the IPv6 interface restarting. It looks like Velocity listens on IPv6, and around the error time the IPv6 interface restarts. This issue occurs every 1-2 days, randomly.

So the logs for around that time, not very useful but:

• Velocity Proxy: https://pastebin.com/dhmpTtEV
• MC Server: https://pastebin.com/Xk41cyMw
• /var/logs/syslog: https://pastebin.com/54qebKKm
• /var/logs/kern.log: https://pastebin.com/NDXZYWga

Note: The MC server and Velocity run one hour behind.

Another thing I have noticed is that this pterodactyl0: port 3(veth8055ae8) entered blocking stateoccurs quite often, pterodactyl is the managing platform I use for the servers.

Server info:

• CPU: Ryzen 2600
• Memory: 16 Gb (2x8) 3000 Mhz
• OS: Ubuntu 18.04 LTS
• Minecraft Version: 1.14.4
• Paper Version: git-Paper-226

I have already disabled the firewall in case that was the issue, which it wasn't. Storage, CPU, Memory or temperatures don't appear to be an issue either.

Any suggestions are greatly appreciated!

Thanks!

If your saying this happens every time the IPv6 restarts have you tried disabling IPv6? It might be the reason like your saying. Not use to using Ubuntu but I believe this is suitable enough since we don’t really use IPv6 yet.
