Summary: Asterisk 1.6.2.16.1 on embedded linux low perfomance
of app_queue
Description:
Hi
I run asterisk 1.6.2.16.1 on embedded linux based on gentoo linux. LAMP &
FreePBX is used.
uname -a
Linux pbx 2.6.36 https://issues.asterisk.org/view.php?id=2 SMP Thu Feb 17
14:00:31 i686 Intel(R) Atom(TM) CPU
N270 @ 1.60GHz GenuineIntel GNU/Linux
Asterisk works with well perfomance. Tests of perfomance of chan_sip &
playback:
sipp -rtp_echo -sn uac 192.168.1.1 -s 777 -d 30000 -l 150 -i 192.168.1.2
with dialplan:

exten => _X.,3,Hangup
asterisk -rx "core show channels"

asterisk -rx "core show uptime"
System uptime: 1 hour, 22 minutes, 6 seconds
load average: 0.62, 1.16, 1.77
Asterisk's PID uses 99% CPU
I think this perfomance is good for this mashine.
Then I test a queue perfomance. In FreePBX i add 15 peers(extensions) &
add queue whith default settings:
asterisk -rx "queue show"
0000001 has 0 calls (max unlimited) in 'ringall' strategy (0s holdtime, 0s
talktime), W:0, C:0, A:0, SL:0.0% within 60s

111 (Local/111 at from-queue/n) (Invalid) has taken no calls yet
110 (Local/110 at from-queue/n) (Invalid) has taken no calls yet
No Callers
The members of this queue are absent. They are not registered on server.
Either in FreePBX I add inbound route 777 to queue.
So, test:
sipp -rtp_echo -sn uac 192.168.1.1 -s 777 -d 30000 -l 5 -i 192.168.1.2
(ONLY 5 CALLS)
& register one of 15 members of queue (peer 100)
well, some time after the running test - all is OK:
asterisk -rx "core show channels"

But after only 1minute, 41 seconds queue is ?eases to call member 100.
Then I see:
asterisk -rx "queue show"

It is not all. After the termination of the sipp, asterisk become strange:
it execute commands whits small delay & want no to execute command "core
restart now". I can restart asterisk only with killing PID.
So, i thik it is a bug.
I tryed to find similar issue on this site before.
