My server's CPU is constantly at 100% and I have no idea why. I'm running Tekkit version 3.1.2, the server has 6 GB of storage and 2 GB of RAM. When I restart the server the CPU will go back down to around 40-50% for a few seconds then it will go back up to 90-100% for a few seconds, then back down to 40-50%. It will repeat this cycle of "use 50%, then 100%" on and on for about an hour then it constantly floats around 98-100% until restart. Does anyone know what could be causing it? I've disabled several plugins that I thought were causing it but it didn't help. If you know of a setting with any of these plugins that will reduce CPU usage please let me know. Thank you.
