Description:Asterisk will crash on the first call I make from a SIP phone out directly after I hangup.  The very odd thing is if I run asterisk with -c, it does NOT crash.  I could not produce a core file with the -g option.

For example, I can run "asterisk -c" and make calls fine.  But if I run just "asterisk" and make a call and hangup, it will crash.

can you get a gdb bt full on this so we can find out what's causing the problem?  Also, try updating to current CVS.
By: twisted (twisted) 2004-04-29 21:12:45

sorry, if you can't produce a core with this, try attaching to the process that's running with gdb and once it enters the crash state, run a bt.
By: Brian West (bkw918) 2004-04-29 21:22:54

once it crashes you can't connect to it. :P

But I have tried to recreate this and I can't

I run asterisk fine and make calls fine, the calls go thru and no crash.

By: Brian West (bkw918) 2004-04-29 21:24:50

I even tried asterisk -g then connect to it with asterisk -rvvvgddd

Don't know wny you would do this but it didn't crash on me either.

What distro?
By: twisted (twisted) 2004-04-29 23:07:02

Also, can you post your AGI here so that we can try to emulate exactly what happens?
By: Brian West (bkw918) 2004-04-30 12:49:23

Your going to have to respond faster on these Major/Crash bugs as they are the only thing holding up 1.0-RC1 so please respond ASAP.

Thank,
Brian

By the way,
"[New Thread 1184528320 (LWP 32627)]"
occurred right after I made a SIP call.

Then,
"Program exited normally.
Segmentation fault"
occurred right after I hung up (I never picked up the call.)
By: Matthew Nicholson (mnicholson) 2004-04-30 16:46:12

I think this has something to do with using agi.  The calls that don't use any agi work fine, but when I have used an agi script on that extension and the call completes asterisk exits.  Like sammy said, it does not happen in console mode.
By: Malcolm Davenport (mdavenport) 2004-04-30 16:50:28

ok, does this problem occur outside of Redhat 9?
By: Matthew Nicholson (mnicholson) 2004-04-30 16:55:40

Yup RH 9...

mnicholson, how many processors?
By: Matthew Nicholson (mnicholson) 2004-04-30 19:07:36

Two processors
By: Samy Kamkar (samyk) 2004-04-30 19:15:11

Same on my machine...I'm wondering if that is part of the problem.
By: Mark Spencer (markster) 2004-04-30 20:18:28

Have you guys tried running under valgrind to find the real cause of the crash?
By: Samy Kamkar (samyk) 2004-04-30 20:43:06

Here is the AGI I'm testing with and it is still crashing:

#!/usr/bin/perl

use strict;
use Asterisk::AGI;

my $AGI = new Asterisk::AGI;
my %input = $AGI->ReadParse();
my $ext = $input{'extension'};

$AGI->exec("Dial", "SIP/$ext\@gwr1");
By: Mark Spencer (markster) 2004-04-30 20:49:03

Can't duplicate.  Find me on irc (kram) and be prepared to provide login information.  Preferably please have valgrind already installed.
By: Mark Spencer (markster) 2004-04-30 23:07:14

It's not crashing actually, it's simply exiting.  The reason is that poll(NULL, 0, -1) actually returns (???) so we have to put it in a loop.  Fixed in CVS
By: Mark Spencer (markster) 2004-04-30 23:07:32
