Crashes when I join my server...

Step 1: Start up run.bat.
Step 2: Launch Minecraft.exe.
Step 3: Join my server at localhost.
Step 4: "Logging in...."
Step 5: "Downloading terrain..."

Have you tried logging in without the mods?
Can you logon to other servers?

 

I was actually just about to post that I am able to log on without mods, meaning that the crashes are my client side mods' fault.
But... My server also has something to do with it, because I can't log on to my server, but I can however log on to any other server.

I uninstalled all my mods except Optifine, and now I can log on. I don't like this, though, so I still need help.

 

I noticed a lot of item frames in the log you posted maybe take a copy of the world then generate new one?

or give your client more memory at startup.
