reposync fails syncing repos on completely unrelated paths (concurrency issue?)


About job

As you can see below

05:35:07 ++ reposync --config=jenkins/data/mirrors-reposync.conf
--repoid=centos-kvm-common-el7 --arch=x86_64
--norepopath --newest-only --urls --quiet

the sync is related to "/var/www/html/repos/yum/centos-kvm-common-el7/base"
using as cache directory "/home/jenkins/mirrors_cache"
but in "/home/jenkins/mirrors_cache" there's

/home/jenkins/mirrors_cache/fedora-base-fc29 error was: [Errno 17] File
exists: '/home/jenkins/mirrors_cache/fedora-base-fc29'

this looks like a concurrency issue, a lock should be used in order to
prevent two instances to use the same cache directory at the same time or
use separate cache directories for different repos.
