Hello, i'm currently hosting some minecraft servers for friends, but i'm currently having some problems with one server. I'm starting my server using Code: java -jar -Xincgc -Xmx15G server.jar nogui The bukkit Version is Code: This server is running CraftBukkit version git-Bukkit-1.4.7-R0.1-b2602jnks (MC: 1.4.7) (Implementing API version 1.4.7-R0.1) The following plugins are running on this server. Code: AutoMessage, Modifyworld, PermissionsEx, AutoSaveWorld, DwDNPC, CoreProtect, Essentials, dynmap, ChatManager, EssentialsSpawn, Dynmap-Essentials But after quite some time, the following is happening. The TPS is getting lower and lower, and the server won't allocate more memory for Bukkit. Ive been trying to switch GC settings, and other stuff but no solution for my problems. Please not that i can't disable the Dynmap plugin, this is mandatory for the RPG. Code: 19:16:38 [INFO] Uptime: 2 hours 10 minutes 35 seconds 19:16:38 [INFO] Current TPS = 16.017317 19:16:38 [INFO] Maximum memory: 15,293 MB 19:16:38 [INFO] Allocated memory: 1,282 MB 19:16:38 [INFO] Free memory: 738 MB 19:16:38 [INFO] World "world": 5,763 chunks, 2,816 entities 19:16:38 [INFO] The End "world_the_end": 0 chunks, 0 entities The server is a 8Core XEON with 26GB's of ram. EDIT; Going to run Jstack to do some heapdumps, will post these when done. Cheers, Chunkr Ran JMX for some time here are some of the results. The Heap Size keeps increasing, even with 3/4 Players it won't go down. If someone could give me a push in the nice direction it would be awesome <3 EDIT by Moderator: merged posts, please use the edit button instead of double posting.
