ssh server problems in 11.1?

I’m having a real problem with intermittent ssh disconnections, anyone else getting this?

It’s the same thing regardless if it’s over ethernet or wireless, and nfs shares don’t have any problems at all.

I don’t use nfs, but I do connect to my mother’s PC in North America from here in Europe. Her PC is running openSUSE-11.1 (my PC here in Europe runs 11.2). Typically when I connect I will pipe vnc through ssh . A week ago I was connected for over 3 hours without any disconnections.
