Great mod btw... Up until last night. If this isn't the correct place to post a bug/glitch/memory leak, I apologize in advance.
A few things in advance:
-I'm running the server on my computer through SP LAN
-Win 7 64 bit
-Latest Java Ver.
-6gig ram w/ 3gig dedicated to Minecraft
-Haven't had any* lag issues up until last night
Anyway, my brother and I are working on getting the End portal set up as well as advancing blood magic in the overworld. He was working on moving spawners from towers using the "random things" block teleporters to make a mob trap for blood as well as other items. I'm working on the altar... At some point last night I start to get horrendous lag and my allocated memory is at 100%. It slowly rises from the point where I start the game to where it reaches 100% and freezes (This only happens in the Overworld at our base). In addition to that, we now have invisible mobs spawning that can't be interacted with or moved unless we turn peaceful on/off.
In our spirit world, my brother moved a zombie spawner from a dungeon to the village we're in (For testing purposes); sat there for days not spawning anything. Right around when the whole can of worms opened, the zombies start spawning from the spawner. So there's that too.
Now I spent a good portion of today trying to debug this so called memory leak. So far we've: removed the spawners, removed the entire mob trap, disabled chickenchunks thinking it was a chunkloader issue, and set it to peaceful. I've seen nothing regarding this issue and nothing we do has fixed the memory leak. I'm all out of ideas here... Any suggestions? Or should I just go back to a previous backup save?
