I'm trying to put together a modpack but I keep getting this log spam (it also appears to crash my game frequently), it appears to be to do with world saving and it these same lines of text appear multiple times a second, they are as follows:

If anyone can help, it would be very much appreciated, I can't tell if this is a Forge bug or a bug in a mod I have installed.

 

Here's the full log (have fun reading that!) (It's over 500kb so I can't put it on pastebin): https://drive.google.com/file/d/0B3-RxJa-bmqAUGJoR3lfNDMwc0E/edit?usp=sharing

 

Note: This happens with both the recommended version of forge and the latest version. I'm using MC 1.6.4

Make sure you do not have any other server processes running.

This ha;penes when two or more MC server are reading from the same folder.

If this is not the case after shutting down ALL MC servers that could possible interact with it go into your world folder and delete session.lock

Thanks, I'll try restarting my computer, there shouldn't be anything else running but I'll try anyway.

Neither method worked, any other solutions? I also noticed it happens every 2 seconds (the normal MC auto-save time)

 

Fixed it, it appeared to be a problem with Galaticraft, I've removed the mod and it works fine now.
