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

[Ioan I. <ioa...@mo...>]

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?
