I’m using jenkins with alot of plugins, also running my selenium cases on same machine so as you guess we have very big tmp folder after each day.
Do fix this issue, i added a cron job, used root access since some files requires it before deleting.
Its not safe and i suggest using another jenkins plugin for task but who cares right? 🙂
sudo crontab -e
30 2 * * * rm -r /tmp/*
There you go.
