Now my process is blocked and I have the case in my hands.
Do you have something to ask me in order to have more details ?

That means it's not waiting in a kernel call right now. Was the program
in the hung state you've observed at the time you ran the command? Its
output would only be interesting when it's hung.

Old kernel, maybe? You're running on some kind of enterprise-y distro,
so who knows how ancient half the stuff in there is.
