Hi, Craig
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 ?

Regards, Andrea

That means it's not waiting in a kernel call right now. Was the program=20
in the hung state you've observed at the time you ran the command? Its=20
output would only be interesting when it's hung.

Old kernel, maybe? You're running on some kind of enterprise-y distro,=20
so who knows how ancient half the stuff in there is.
