I recently switched to Spigot around a month ago because we got out of memory errors TONS, on 2GB of ram server, the issue started out of the blue we always ran just fine before its just now its choking and crashing every other hour. We recently upgraded to an 8GB dedicated CentOS box, and after about 1 hour of game play it will kick all players for end of stream, and all the IP's lose connection and server is inaccessible for around 10-15 minutes, what I'm asking is why? Could it be a DDoS, and if so how can I block it? I start it and it automatically eats up 3GB of RAM, then slowly but surely eats the rest till players get disconnected, no errors from console, just severe lag then crash. I can reboot it after about 10 minutes, but if I don't it comes back in about 15-20 minutes by itself, no reboot just completely normal from before aside from around 15-30 /###.###.###.### lost connection in console, and each user disconnected for end of stream. We run 4 worlds and these plugins, and all are mostly recent worlds aside from our main which has been the same for around 8 months with diameter of 14000 blocks. (Current build of Spigot, 1.4.7 r1.1) Ships, TuxTwoLib, PVPGun, Multiinv, Worldedit, Essentials (spawn, core, chat), PEX, Factions, Citzens, SnoGro, AutoAnnouncer, LogBlock, LWC, Worldguard, Craftbook, AutoCraft, Vault, AdvIPLog, MCMMO, Dynmap, Chestshop, WorldBorder, Multihome, Multiverse-Core, Stargate, Votifier, Voxel Sniper and Spacebukkit (The issues were before SpaceBukkit, and continued after a change test) Any help is much appreciated, we have run out of options and may just shut down due to the stress and loss of player base. Thanks!
