I'm running asterisk on a small box, [1]Intel-R-_Atom-TM-_CPU_330_@_1.60GHz
and when I try to restart the asterisk it fails.
/etc/init.d/asterisk restart
* Caching service dependencies ... [ ok ]
* Killing wrapper script ... [ ok ]
* Stopping asterisk PBX gracefully ...
* Waiting for asterisk to shutdown .............................................
................
* Failed.
When I run /etc/init.d/asterisk status
I get: "* status: started"
At this point I have to kill the process ID
"zap" it (/etc/init.d/asterisk zap)
and restart it.
Why asteriks can not shut down properly?
How can I monitor this process and restart it?
I don't know what's in your startup script, for I never used one, but
it says about graceful shutdown.
It might be executing "core stop gracefully" or maybe "core stop when
convenient"
In the first case, Asterisk will stop receiving new commands and calls,
will wait for all current calls to disconnect and then shutdown.
In the second case, Asterisk will continue receiving new calls (not
sure about commands), and as soon as there are 0 active calls, it will
shutdown.
As you can see, in the second scenario you'll rarely get to the
shutdown on active server.
Not sure why do you kill the zap process. Does it hang up? For when you
kill it and drop all Zap calls, asterisk may already rest in piece, if
my above guess is right.

It does the same thing on my both servers, the one I've mentioned above and my
AMD 8-core server.
The environment is not busy but I've notice it that it does it when I don't
restart it for a few days or a week.
When I start from fresh I can restart it and it shuts down and restart
correctly.
If don't "zap" it I can not start or restart the asterisk as it keeps telling
me that the process has been started; so I have to zap it first.
