Yeah this is a lock which is always in our cache, cant figure out why it's there, but when I delete the lock and the other files, they always reappear when I run a new clearml task.
Another thing I should note: I have recently had an error which fix was to run git config --global --add safe.directory /root/.clearml/vcs-cache/r__ (git repo name).d7f
Ever since, once I run a new task - a new file appears in the cache with the format of <git repo name.lock file name_a bunch of numbers>
