[Asterisk-Users] can't CLI> STOP NOW by zombie MOH

[Zen Kato]

I am using CVS-v1-0-04/20/05-12:31:26. Windows Messenger5.1 works MOH
fine. After I stop MOH on Windows Messenger, if the hungup signal could
not send to *, the sip channel(e.g.,SIP/52001-08ca) for this MOH remains.
Then the user trys again MOH, a new sip channel starts. And again
the hugup signal can not send to *,.........

When I 'stop now' from CLI> , * cleanups the remaining sip channels as follows;

*CLI> stop now
Beginning asterisk shutdown....
    -- Stopped music on hold on SIP/52001-9e3b
  == Spawn extension (sip, 6000, 2) exited non-zero on 'SIP/52001-9e3b'
    -- Stopped music on hold on SIP/52001-08ca
    -- Stopped music on hold on SIP/52001-63fd
  == Spawn extension (sip, 6000, 2) exited non-zero on 'SIP/52001-63fd'

Executing last minute cleanups
  == Destroying any remaining musiconhold processes

The CPU goes to 99% usage, but can't stop mpg123 and asterisk,
the following 'top' show ;

 5737 root      25   0  3832 2588 2424 R 99.7  0.5   2:54.00 mpg123

 5627 root      15   0 47988 6604 3624 S  1.3  1.3   0:15.64 asterisk
 4673 root      17   0  8588 6820 1620 S  0.3  1.3   0:02.05 hald

 5551 zenkato   15   0 58500  17m  10m S  0.3  3.4   0:01.20 gnome-terminal
....(snip)...

So, I have to do 'kill -9 pid-of-mpg123'. * goes to segmentation fault.

Is this safe way to stop asterisk?

When UA could not send 'hangup signal' to *, the following warnig came out
console.
