So, recently I've been getting these spammed in console: http://gyazo.com/eb840d672dec9b2e46a90a10d21465bb , Every few seconds, it spams this, with different random IPs(but the IPs repeat), and random ports. I've checked every server list website that I posted it on, they're all fine. I updated my plugins and checked the configs for any type of option that might have to do with pinging the server, I can't seem to figure it out. I also tried banning the IPs, with both the Essentials IP ban (/banip <IP>) and the standard Minecraft / Bukkit one (/ban-ip <IP>), and the IPs that I ban still come up. I've tried googling the IPs to see if I could maybe figure out where it's coming from, as expected, no luck there. I have no clue what to do to fix it, I've contacted my host, they don't know either. It seems to have started when 1.7.2 came out. If anyone has had this issue and knows a fix, or knows what's causing it, please help. Thanks.
