Thank you so much for this! I have been so infuriated the last couple of months with persistent issues like Mail closing and Safari’s cache randomly being purged, losing many website’s login sessions. Two-factor authentication multiple times an hour gets frustrating very fast! I was really struggling to search for the problem on the web, “Safari forgets website logins” led me nowhere. I was almost at the point of just trying a reinstall of macOS. Indeed, my MacBook’s disk is pretty low on space. Not dire, but fairly low. I will clean up and hopefully things will return back to normal! EDIT: Some users mention RAM and the OOM killer on Linux. I don’t think the situations are quite the same. It’s possible for a machine to have low disk space without any RAM pressure. I assume that is what is happening on my machine. When Mail started dying on me I considered and checked the RAM use, closing a lot of backgrounded applications, and even going so far as to reboot the machine without success.
