[Astlinux-users] Astlinux 0.4.5 on Via EN12000EG - asterisk SIGSEGV

From: Ioan I. <ioa...@mo...> - 2007-05-23 19:53:18

Hello,

I am just installed Astlinux 0.4.5 on a Via EPIA EN12000EG Mini ITX fanless 
system and trying to made some load tests.

As this is our test system we have 1 GB memory and we run with a 40 GB SATA 
drive (boot=sda1 and kd=sda2).

First I had to insert in rc.modules via-velocity module in order to 
recognize the Ethernet Gigabit Via VT6120/VT6121/VT6122. (this is mentioned 
here just for reference).

Next I tried to load a little bit the system and found that asterisk receive 
a SIGSEGV signal and get "Killed" (literraly this is what I receive on CLI). 
Using Sipp on another machine (with rtp_echo) and generating 3 minutes calls 
(with .call files I generate a SIP call to a WaitMusicOnHold(300) extension) 
I found that at near 44-46 simultaneous calls asterisk crashed without any 
visible indications in logs (with verbose and debug set to 10).

As I not a Linux expert and not very familiar with Astlinux the only idea 
was to use strace and here is the output:

pbx ~ # uname -a
Linux pbx 2.6.16.12 #1 SMP PREEMPT Sun Apr 22 12:16:58 EDT 2007 i686 unknown
pbx ~ # strace -p 31201
...
--- SIGRT_1 (Unknown signal 33) @ 0 (0) ---
sigreturn()                             = ? (mask now ~[TRAP KILL STOP])
getppid()                               = 31200
wait4(-1, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], WNOHANG|__WCLONE, NULL) = 
31563
munmap(0xb7e00000, 2097152)             = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
Process 31201 detached

Do you have any recommendations on how to trace the problem? How could be 
analyzed a core file on Astlinux?

Ioan,

  I like load tests!  Thanks for asking what to do about this - make
sure that you ask us any other questions you might have.

  When doing load tests you probably have to tweak ulimit before you
start Asterisk:

http://www.voip-info.org/wiki-Asterisk+debugging#ulimit
http://www.voip-info.org/wiki/view/Asterisk+dimensioning

  I have always wanted to work this into AstLinux somehow...
Unfortunately because most systems don't have any swap space we have
to be very careful with memory consumption.

  However, if you want to add some swap space (if you need it), all of
the utils are there:

mkswap
swapon
swapoff

From: Ioan I. <ioa...@mo...> - 2007-05-23 20:30:35

Hello Kris,

Thank you for your quick answer and tips. Still I do not think it is a 
problem on ulimit.
I verify fds for asterisk pid and was less that 1024. Also, for generating 
the core I run unlimit -c unlimited....but this is just to get the core. How 
to debug it?

Regarding swap - I see (with free) that there is plenty of free memory. So 
no need for a swap. Or am I wrong?

Bellow you have some data from such a crash:

Re: [Astlinux-users] Astlinux 0.4.5 on Via EN12000EG - asteriskSIGSEGV

From: Ioan I. <ioa...@mo...> - 2007-05-25 09:46:22

Hello,

Any idea on how to debug the asterisk crash?

Last test was running 2 cps with calls of 10 sec (resulting 20
simultaneous G711 calls) and after aprox. 3 hours asterisk crash. Same
behaviour - no "visible" traces.

If no other ideas I will configure some swap space and try again.

Best regards,
Ioan.

Re: [Astlinux-users] Astlinux 0.4.5 on Via EN12000EG - asteriskSIGSEGV

From: Ioan I. <ioa...@mo...> - 2007-05-30 13:02:48

Hello,

I come back with the following report:

1. I add some swap but I experience the same crash (asterisk segmentation 
fault at 46 simultaneous SIP calls - with or without RTP traffic).

2. In order to avoid any discussions regarding Sipp, I create a simple test 
scenario:
    a. extensions.conf
        [test]
        exten => 000,1,Answer
        exten => 000,2,Echo
        exten => 000,3,Hangup

        exten => 001,1,Answer
        exten => 001,2,Playback(demo-congrats)
        exten => 001,3,Hangup

    b. create a call file (/tmp/test.call)
        Channel: Local/000@test
        MaxRetries: 0
        Context: test
        Extension: 001
        Priority: 1

    c. Start the test:
        in one terminal run:
         # watch -n 1 asterisk -rx "show channels"
        in the seccond terminal run several times:
         # cp /tmp/test.call /var/spool/asterisk/outgoing/`date +%s`.call; 
free
        this will add 2 active calls.


Result of the test: On our PBX (astlinux 0.4.5 on Via EN12000EG), asterisk 
crash at the transition from 46 to 48 channels:
....
pbx asterisk # cp /tmp/test.call.orig /var/spool/asterisk/outgoing/`date 
+%s`.call; free
              total         used         free       shared      buffers
  Mem:       971136        37144       933992            0         1396
 Swap:      2097136            0      2097136
Total:      3068272        37144      3031128

pbx asterisk # cp /tmp/test.call.orig /var/spool/asterisk/outgoing/`date 
+%s`.call; free
              total         used         free       shared      buffers
  Mem:       971136        32704       938432            0         1396
 Swap:      2097136            0      2097136
Total:      3068272        32704      3035568


Could anybody confirmed that using astlinux 0.4.5 on their system, they 
could have more than 48 active calls using this simple test?

Best regards,
Ioan.

Hello,

What is the codec used : alaw to gsm ; ulaw to G729 ... ?
Have you modify tmpfs sizes in rc.conf ?

You'll need to be very careful there.  From prior emails, Ioan only has 
128MB of ram on this machine.  If you increase /tmp or /var which are 
both tmpfs file systems, your available ram will be reduced as the 
partitions fill up.  It would be interesting to repeat the same test 
with more memory (say 512MB) and increased /tmp and /var partitions.

Re: [Astlinux-users] Astlinux 0.4.5 on Via EN12000EG - asteriskSIGSEGV

From: Ioan I. <ioa...@mo...> - 2007-05-30 14:09:04

Hello Mathias,

1. I use no transcoding.
In Sipp tests I use the standard uac_pcap (using alaw g711a.pcap file)  and 
uas with rtp_echo scenarios.
Also, as I have mentioned I run uac+uas scenario (with no RTP traffic) and 
asterisk crashed with segmentation fault.

I have core files but I do not know how to debug them.


2. Regarding tmpfs sizes - I do not modified them and here are the current 
settings:

pbx asterisk # df -k
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/sda1                63413     57044      6369  90% /
none                       200         0       200   0% /dev
none                      5000       192      4808   4% /var
none                     10000       184      9816   2% /tmp

Ioan,

  You will have to load that corefile into gdb.  I will try to compile
an AstLinux gdb for you today.

Hello Darrick,

Our machine have 1GB of memory - so I think it is more than enough. And as 
you seen from my "free" reports, only 35-45MB are used.

/var and /tmp was never full (I monitor them carrefully).

Maybe I miss something?

Ioan.

Whoops!  My bad.  I was up til 4:30am last night so I'll blame it on that.

I was only making the comment because I wouldn't have wanted you to run 
out of system memory (when I thought you only had 128MB).  With 1GB of 
ram there would be no problem in making those partitions larger (using 
the variables in rc.conf), but as you say, you're not filling those up.

Are you running the VIA or generic i586 image?
