asterisk users - Jul 2005 - asterisk showing more than once on ps

Guys.

Anybody know why sometimes on some servers Asterisk shows more than once
while doing a ps?

[root@server2 akrall]# ps -ax|grep asterisk
20555 ?        S      0:00 /bin/sh /usr/sbin/safe_asterisk
20557 ?        S      0:00 asterisk -vvvg -c
20558 ?        S      0:00 asterisk -vvvg -c
20560 ?        S      0:00 asterisk -vvvg -c
20561 ?        S      0:00 asterisk -vvvg -c
20562 ?        S      0:00 asterisk -vvvg -c
20564 ?        S      0:00 asterisk -vvvg -c
20565 ?        S      0:00 asterisk -vvvg -c
20566 ?        S      0:02 asterisk -vvvg -c
20567 ?        S      0:00 asterisk -vvvg -c
21958 ?        S      0:00 asterisk -vvvg -c
30470 pts/2    S      0:00 grep asterisk

Im running asterisk via the start/stop script on init.d

On my other servers, it only shows once...

I would guess its the use of the -c flag to run it
 
From: http://www.voip-info.org/tiki-index.php?page=Asterisk+options
# asterisk -vvvvvvc:Start Asterisk PBX, don't go background

have you been monitoring it from the command line. 
I use -rvvvv to get the background version.

Just a guess.

Actually this is on an enterprise system - I have never seen more  
than one. Just checked now and there were several calls up and only  
one ps.

The system startup script /etc/init.d/asterisk calls the script
/usr/sbin/safe_asterisk

In safe_asterisk, the program is started with -c by default (console on
TTY9).

That explains why it is starting with a console, but not why it's
running so many times!  Here is what my system (FC3) shows:

[root@pbx sbin]# ps ax | grep asterisk
 3371 ?        S      0:00 /bin/sh /usr/sbin/safe_asterisk
 3417 ?        S      0:00 asterisk -vvvg -c
 6846 ?        S      0:00 asterisk -vvvg -c
 6848 ?        S      0:00 asterisk -vvvg -c
 6849 ?        S      0:00 asterisk -vvvg -c
 6850 ?        S      0:00 asterisk -vvvg -c
 6853 ?        S      0:01 asterisk -vvvg -c
 6854 ?        S      0:00 asterisk -vvvg -c
 8479 pts/1    S+     0:00 grep asterisk


Can anyone explain why asterisk is being launched 7 times?

Thanks,
OCG

Not quite. RedHat Enterprise also = many at times, depending on number
of concurrent calls; usually one when idle. Maybe it has something to do
with kernel 2.4 vs 2.6 and how threads show up in ps.

That's

But that doesn't explain why, on the same machine, if you call 
"/etc/init.d/asterisk stop"
and then "/etc/init.d/asterisk start", you dont many processes, just
one.
Shouldn't this
be consistent with your explanation?
