I maintain a small fleet of CI machines (mostly macs) and run into this issue as well from time to time. The free space idea is nice but I ram into the problem that under very critical disk space I can’t even shh or when delete a file because there is simply not enough space to execute the simple command. A reboot to get rid of some temp files helps me in these situations to get some control back.
