Got the same problem too. Server runs though, so it doesnt cause crash. Still wondering though what this causes.

So no help or tip on what it could be?
This error occurs each time the server starts even though it is running just fine.

Looks like Forge is unable to load a part of the Misc Peripherals mod on startup. I'm not knowledgeable enough to know what would cause this however, have you checked that the mod file for Misc Peripherals is not corrupted and that you're running the latest version of Java?

I don't know how to check whether it is corrupt or not. However I doubt it as the size is the same as in pack.
Here is my java version:
Code:
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)
Wonder if this is related to wireless redstone somehow? As the world leaks happen too each time.
Honestly i dont know how it affects the world or the system. Have been able to play the game just fine so far.

I believe that the world leaks error is simply a warning directed at mod developers and doesn't mean that you have done anything incorrectly. I just checked and this error is in my startup log as well, so hopefully its just something that will be fixed in a future modpack update.

Ah good to know, think this question is pretty much solved then.
Hope OP is still here. :D
