Problem Unleashed Server Spawning Ridiculous Amounts of Mobs

[onsmirnov]

Hey,
I'm running a FTB Unleahsed 1.1.3 server locally on my computer with 2gb of ram.
I also have bukkit forge installed with essentials.
The server originally ran fine but now spawns wayyy to many mobs which lags the server until it crashes. For example when i looked outside my hosue there were over 100 blue slimes and when i did /butcher i killed nearly 45k mobs.
Is there a way i can limit the number of mobs and am I going to have to remove essentials?

Still looking for an answer :s My record now is 100k mobs butchered

Nobody know whats causing this? I might have to remake the world....

Try switching from BukkitForge to MCPC+ and instead of butchering all the mobs next time, just set the server to peaceful.
