If the server is hung at this point, it was doing something: recovery
from a crash, and during that period it will not respond to statements
until it's finished as you noted. That can take some time, could run
into the minutes. And if you kill it, next time the process starts all
over again having made no progress.
I'd try starting the server again, confirm it's only after this point it
pauses at, watching if it's doing something with "top -c", and grab some
backtraces of what it's doing then. In this sample you gave, the
shutdown was too fast for the server have done very recovery before it
was killed off. It may just be you need to let it sit there for a while
to finish recovery and then it will be fine again, can't tell from the
data you've provided so far.
