Interesting. At the time of the hang, can you still establish
another connection to the box? I'm guessing this is similar to
what I'm seeing on recent current. I think the problem appeared
some time between (UTC+0200):
drwxr-xr-x 2 root wheel 23552 Sep 19 11:38 kernel
drwxr-xr-x 2 root wheel 23552 Sep 12 08:10 kernel.old
Some of my connections hang, but others still function and I can
make new connections.
Sorry, that this is just a "me too".
