Don't know if it has anything to do with it, but quite a few write actions seem to end in stalling. But so do other actions, like sudo. Via another ssh session, I can then see what's happening and either kill the action or let it go on. Quite annoying and causes a lot of delay in waiting and then see if something is still getting on.
