Mail suddenly eating up all my RAM

So I suddenly get a message on the screen that my memory is full, and when I open activity monitor, it showed me that mail was using up 108 GB of my memory. I force quit it and that fixed the problem, but why did this happen in the first place? I use a M1 Max MacBook Pro, and this has never happened before.

MacBook Pro 16″, macOS 14.1

...mail was using up 108 GB of my memory....


As that Macbook Pro model has usually 8 to16GB RAM, "108GB" sounds like a reporting error.


Restarting is a highly overlooked step in keeping a computer happy. I do it once a week on my Macbook Pro.


Are you running any anti-virus or so-called "cleaning" apps. They could induce reporting errors because they compete with elegant protection you paid Apple good money to build into macOS, designed to cover all protection and maintenance tasks.


Catlike, Macs clean themselves quite well.

If this is a one off glitch I would simply ignore it.
