About The Exit Code 128

Hey guys,I used git tool to download the source code about one month,but today,i can't pull the code from server,here are the error tips:

git.exe clone --progress -v "https://hsam@bitbucket.org/sym1987/ctow.git" "D:\CTOW\ctow"

Cloning into 'D:\CTOW\ctow'...
remote: Counting objects: 4767
remote: Compressing objects: 100% (4496/4496)
Receiving objects: 11% (533/4841), 892.00 KiB | 2 KiB/s
fatal: early EOF
fatal: The remote end hung up unexpectedly
fatal: index-pack failed
error: RPC failed; result=18, HTTP code = 200

git did not exit cleanly (exit code 128)

Hope your guys give me help,thanks!
