Hi all,

I am also seeing 100% CPU load from SSH when using it with autossh to set up port forwarding in the background (no X11 forwarding involved):

/usr/bin/autossh -M 0 -N -o "ServerAliveInterval 30" -R $IP:$PORT1:localhost:443 -R $IP:$PORT2:localhost:80 $USER@$HOST -i $KEY

This only recently started with the latest 'apt upgrade'.

If I use

        ssh -XAf localhost xterm

to run a second xterm, then ssh eats up 100% CPU after closing the
first xterm.

Same happens for xeyes or other XWindow apps. It doesn't have to be
localhost, either.

"nohup ssh -XAf ..." seems to work, but for Bullseye it works very well
without nohup.

SHELL is bash 5.1-6
