[size=16px] So as you can see the bottom 23 lines or so look very familiar as the were the lines that told me my other world was corrupt, but the other lines on top really baffles me so please could someone help, thanks [/size]
[size=16px]Ps the lines, the "at atn.c(SourceFile:2579~[1.8.3.jar:?]" were deleted these lines in quotation marks might be deleted as well.[/size]

Those log messages indicate that something had files in the save "open".
It could be a second instance of Minecraft (perhaps Minecraft didn't shut down 100% one time, then the next time you started MC you might see this).
Or it could be an editor (e.g. mcedit) or map utility that is 'using' the save files.

Cool thanks I did have the world file open and when I saved and it didn't respond I got a bit scared ha ha, anyway do you know why this keeps on happening (by this I mean the bottom 11 lines of the log)? It seems that when a world gets corrupt this happens which I'm extremely annoyed about I mean how are you going to play survival when every time you play your world gets corrupted? Thanks NemoTheFish I already know that but thanks for trying to help

The bottom 10 lines of the log (game not responding when saving and quitting) only happended AFTER the release of 1.8 before this these problems have not occurred not even in the guardian temple snapshots, please help

I'm having the same problem. I am using a heavily modded server running Ubuntu Linux 14.04 with java 8 update 45. Using inecraft 1.7.10 and Forge 1.7.10-10.13.1373. I have tried rebooting multiple times, killing all processes with "java" or "minecraft" in the name, and even creating a copy of the entire server (cp -r server1 server2) I notice that on the two occasions I managed to log in, all of my Minefactory Reloaded rubber tree leaves were replaced with autoboarding rails (also MFR) Could anybody help me?
