git log --stat - takes an unexpectedly long time, how to fix it?

Question

git

On one of the servers, git suddenly began to eat 1 core to its fullest and hang (well, or think for a long time, I didn’t wait more than 5 minutes), actually on these commands:

git log --stat
git log --numstat
git log --shortstat

What can be wrong?

ps git version 1.7.1

Answer 1

strace?

Answer 2

git fsck? It is strange that it does not read files from you, but just CPU 100%. It can't be that the repository is just broken? Well, your version of the git is not the latest at all, maybe they fixed something in newer versions.
