So, i am working with a FTB Unstable server, im not entirely sure if this is a modpack conflict or a forge issue but this started to happen once the pack updated to forge 1757 http://pastebin.com/61MV8UZk i have been trying to figure this out for so long, people have said to use nogui yet i am using it, i've bumped the memory to 6GBs, still nothin, changing the GC to use xingc command if i remember correctly is what it's called. I can leave it on for a while with no problems but after a while i start to get console messages saying that the server can't keep up/is overloaded. im 90% sure my pc is fully capable of running this pack. im not sure if it's a memory leak or what, but just recently i got a java heap space crash with no crash log whatsoever. If there's anymore details i am forgetting, just let me know and i'll see about getting more logs!

Alright i figured out the crash, it was Factorization, i reverted it to an older version and it works perfectly now! thanks for the reply!

Everytime a Creeper, tnt, or even Wither, explodes, the server crashes with: http://pastebin.com/zTGBG6WG I have done some research and tried everything but it still seems to persist. I currently have forge removing entities that error but it's annoying when a wither explodes and does the exact same thing. The pack is launched with Technic and i am the modpack creator. im not sure if it's a mod i am using orr what but yea. im going to guess it's a mod, just not sure which one. Any help will be appreciated! if there's more information you need, then just say so! - Growlith1223
