lock file exists

-rw-rw----. 1 root rudder 0 27 mai   12:37 /var/rudder/configuration-repository/.git/index.lock

restarting the webapp doesn't solve it

removing the lock file, and retying t archive everything lead to an unending spining wheel, but it does finish to archive, and deletion of node also succeed

it's probably that the git is really slow

# git --version
git version 1.8.3.1

git gc doesn't improve perf of git

git repack -d doesn't improve neither

Workaround: removing lock file /var/rudder/configuration-repository/.git/index.lock
