I've had massive lags in an area of my map for a while now and decided to see if I could figure out what the problem was using McEdit. So I download, install and open my world and find that there's two areas in the huge lage where it lags the most filled with squids! I deleted 150 squids - and voila! Server lags gone! I worry that they'll come back and cause lags again, perhaps other places on my server as well. I know how to handle the problem now, but according to acopalypse_r on the minecraft forums, this is a bukkit bug. I'm not sure if you guys know about it, so I'm just giving you a heads up and hope that you can fix the problem with squids spawning en masse. I'm currently using only vanilla craft bukkit and dynmap, but have been using the following mods around 1.3-1.4: NetherGate Permissions CrowdControl Spells Wandmin Reference this thread: http://www.minecraftforum.net/viewtopic.php?f=17&t=267807
