while looking, moving and copying files on my Raspberry PI running OSMC i suddenly lost communication and got a "restart" dialog.
I aborted and opened tried to open a new session and got a strange message about memory corruption ( from WinScp - but thaught it was from the Raspberry first - looked like a "login message" )
after that, the session was totally hung.
I created a dumpfile before killing the app.
good luck !
