That suggests to me the problem that you're having is a race condition - you're trying to start x clients too quickly, so sometimes they fail to get a lock on the Xauthority file.
Accordingly, I am inclined to consider this not an ssh issue. Matthew -- Rapun.sel - outermost outpost of the Pick Empire http://www.pick.ucam.org
