Description

Often the push from a client to the gitea remote get stuck for a lot of time. Looking at the log I found this

This temp index folders are empty, I’ve tried to remove that but I can’t until I stop the gitea service. This take a lot of time and sometime even fail and I have to terminate the gitea process from the task manager. During the stop of the service this lines are added to the log, even after a restart without any remote push
