There are sometimes you will get some errors in /var/log/syslog.log saying IPV6 Neighbor Table Overflow and which are really annoying. For fixing this you should follow this.

I got this error in my Debian-7 vps. I have been assigned 6 IPV6. This error was making me crazy. However, i did find the solution and here it is. You have to add below lines in the sysctl config file. Add those lines in the end.

And better reboot your vps.

Thank You.
