For the past week or so my players have been experiencing random lag on their ends. It's causing all sorts of problems with my plugins like Nocheatplus detecting them as hackers since they're all lagging which causing them to get kicked, warned, or even temp banned for trying to break or place blocks while lagging or trying to use commands while lagging. I'm not sure on what's causing the lag at all since I'm not running any intensive plugins in my opinion. I've ran 4 different Nolagg examine test, if you'd like to view those, I've included a .zip file download on this thread. http://forums.bukkit.org/attachments/4-zip.11660/ You can view my Worldguard report here for more server details: http://pastebin.com/jL0St7KZ The lag issues just started and it usually happens at random and goes away after I run a server restart. A friend of mine took a picture of his lag meter and: I've pretty much tried every troubleshooting technique I can think of. This has been happening for about a week I'd say. I've had this same server setup since the first 1.4.2 Bukkit release and I wasn't experiencing any problems then until now. Other details: Using a 1G port connection 4GB ram allocated towards server Any help or suggestions?
