Ahoy. I've been serving for about a year now, I've had many problems and found many solutions, but suddenly when I run my server I continuously get this warning message. I have 7gb of RAM dedicated to the server, it's a dedicated machine with an i3 sandybridge CPU and it's never had this problem before. When I log into the server (locally) all mob movement is really jerky and it feels like you're running in slow motion (very slightly). I've disabled all of my plugins and it still does it. I looked through a quick Google search and the only solution I found was to increase RAM usage to 2gb or so, considering it was already on 7 I assumed that that wasn't the problem. Can anyone help me? Looking at the server now (through teamviewer on my second monitor) I've noticed that the message comes every 19 seconds. And I have tried turning it off and on again.
