Details of the issue:

Hey guys,
after 120 hours playtime, my IE:Skyblock 1.1 world has starting to crash down to the desktop.
Till now, it's not reproducible and seems to be random for me.

I tried to update my java to Build 1.8.0_91-b14, and reinstalled the ftb launcher and the modpack (backuped the world), but got
the same crash down.
I'am playing on a Win7 64, and my gainward phantom gtx 970 got updated recently.

Here's the error log. I hope someone can figure out, what causes this type of crash.
thanks for any kind of help/advise!

greetings
chris​
