Every once and a while a server will decide to max out one core to 100%, sometimes it decides to max them all out to 100%. In turn that eventually causes crashes, as you can imagine, but i cant find a solution. Here are my timings for all of the servers. Hub server: http://paste.ubuntu.com/5644011/ http://aikar.co/timings.php?url=5644011 Deathban Server: (Has not caused 100% CPU) http://paste.ubuntu.com/5644013/ http://aikar.co/timings.php?url=5644013 Creative Server: (Has Caused 100% CPU) http://paste.ubuntu.com/5644016/ http://aikar.co/timings.php?url=5644016 Assassins Server: (Has Caused 100% CPU) http://paste.ubuntu.com/5644017/ http://aikar.co/timings.php?url=5644017 Survival Server: (Has not caused 100% CPU) http://paste.ubuntu.com/5644019/ http://aikar.co/timings.php?url=5644019 SkyBlock Server: (Has Caused 100% CPU) http://paste.ubuntu.com/5644020/ http://aikar.co/timings.php?url=5644020 All of the servers are running spigot build #715. VPS Details: 64GB DDR3 RAM e5-1650 CPU 6 cores and 12 threads 2x120 GB SSD 2x 2TB SATA III Running a MySQL database off of the VPS also. Most of the plugins being connected to it seem to be higher percentages in the timings, especially TopPVP. This has recently started acting up after all of my servers had been updated to 1.5. That would be about 5 days ago. I dont know how to read timings extremely well, so i was hoping someone could tell me if there was fatal error going on. If you need anymore information, please reply here.
