sshd exits after inactivity

I turned on Remote Login to access my M1 Mac mini via SSH. This works as expected but after 2-12 hours of inactivity sshd exits and I'm no longer able to login.

This has been happening every night, without fail, since I setup my Mac about two weeks ago.

In an effort to debug the problem I wrote a small web service that allows me to reboot the Mac and dump the output of `ps ax`, which temporarily allows me to login and is how I know that sshd is not running after some inactivity.

Anyone have ideas about what I could try to get Remote Login stable?

Mac mini 2018 or later

Turn out the issue here was Little Snitch, uninstalling it fixed the sshd shutdowns I was seeing.

Still feels like the server should automatically restart if it crashes, but it probably makes sense to make the server relatively easy to shutdown temporarily.
