mpd has hung

[Alexander Shikoff]

Hello All,

I have mpd 5.3 running on 8.0-RC1 as PPPoE server (now only 5 clients).
Today mpd process hung and I cannot kill it with -9 signal, and I cannot
access it's console via telnet.

State of process in `top` output is STOP:
73551 root          2  44    0 29588K  5692K STOP    6   0:32  0.00% mpd5

Is there a way to stop a process without rebooting a whole system?
Thanks in advance!

P.S. I'm ready for experiments with it before tonight, but I cannot
force system to crash in order to get crash dump right now.
