engine fault on channel 2, recovering...

The easiest way to reproduce is to leave the computer alone for a while and
more often than not, the KDE desktop will lock up. But it also locked while I
was actively using it about 1/2 hour ago.

I used to be able to ssh in and type "init 4 ; init 5" and successfully restart
KDE. Unfortunately, someone made SSH access tighter recently and I can no
longer do that ("Connection refused").
