Problem Agrarian Skies crash

[Shmeeb]

Running Agrarian Skies v 2.1.9 with Cauldron B10, and I've been getting this crash for awhile, and I have no idea what is causing this.

Crash: http://pastebin.com/HAJm3LmC

Any ideas what's causing this?

 

[UnionCraft]

Were running into this issue too, server doesnt crash or create a crash report it just times out.

I'm not entirely sure but Opis might be a cause, I remember reading from blood that Mobiuscore needs updating (only server side)

It could be Mobiuscore (or opis), but I'm using version 1.2.2 (which is what blood suggested)

 

[UnionCraft]

I disabled Opis for the time being, it seems to have solved the issue for now.
That being said we are still running off MCPC+ (not Cauldron new versions yet). Not sure if its related.
