Leak in file backed swap

[Giulio Ferro]

Hi folks,


FreeBSD 11-Stable recent build.


I've set up a FreeBSD instance in AWS with 1GB RAM.

Since I needed some more, I decided to create a swap partition (there 
are none by default on AWS)

and I created a 1GB file under /usr on the instance FS and proceeded to 
mount it as swap.


Even if the machine isn't doing anything, after one day or less the 
machine becomes unresponsive

and must be rebooted.


I solved this by buying a 2GB instance, but maybe this issue may be 
insteresting for someone to look into?
