I have a Jetson Nano, which serves mostly as a DLNA music server. From time to time I log in and poke around. It's been slow to do its business lately, and some commands that should be fast are slow - very slow.
How slow? Try 25 seconds of idle time before w returns.
It's not hard to find this 25 second timeout show up in other people's problems - some accounts run like so:
- systemd-logind: Logins via ssh and su are delayed by 25 seconds
- SSH login delayed by 25 seconds with pam_systemd(sshd:session): Failed to create session: Connection timed out
The problems point back to dbus, but don't have a single simple diagnosis or fix. And indeed I did something on the Nano and the problem disappeared.
As I say, mysterious.
