asterisk users - Jul 2010 - Asterisk Crashes - Segmentation Fault

Hello Team,

I was looking for audio conferencing solution where i got Web-meetme.
I had installed Asterisk 1.6.2.9 on Centos  5.4. Its perfecting working
fine. I tried using Meetme even meetme app is working perfectly fine.
I installed Webmeetme 4.0 and integrated with my asterisk. When i try to
dial the conference number it take me to an IVR wherein it asks for the
conference number. The time i provide the conference number, asterisk
crashes giving segmentation fault.
I have been trying to google up and checked lot of forums but didnt get any
solution for this yet.

Kernel version -- 2.6.18-194.3.1.el5PAE

Hi

If you get Segmentation fault. One of core.$$$$$ file is created.

Try to use # gdb asterisk core.$$$$$ and use bt command.

And then paste error here.

Which instructions did you follow for the integration?  Are you using
RealTime enabled app_meetme or app_cbmysql from the WMM package?  Which
exact version of WMM?

Dan

Hi Dan,

I can see the path does exists but i cant see any recordings happening inn
there.
There are no files in it

Following is the output:

/var/lib/asterisk/sounds
drwxrwxrwx  2 asterisk apache   4096 Jun 27 20:54 conf-recordings

I hope m understandly this correctly but m sure m missing something here ;-)

Yes, read doc/backtrace.txt.  It will explain how to generate an
unoptimized backtrace, then uploaded it to the mailing list.

You did understand, and we have eliminated another of the possible
issues.  Are you assigning an admin pin to these conferences?
There is a patch that allows recording pinless concenferences, but is
has oddly not been merged yet.  Try setting an admin pin.

If that does not work, send the CLI output with core set verbose 5 as
you dial in to the conference.

Dan

Hi Dan,

I did added the record option in user options as well.

$Mod_Options = array(array(_("Announce"), "I"),
array(_("Record"), "r"));
$User_Options = array(array(_("Announce"), "I"),
array(_("Listen Only"),
"m"), array(_("Wait for Leader"), "w"),
array(_("Record"), "r"));

And the gre8 news is, it did worked this time. But it saved the recorded
file in the following path:

/var/lib/asterisk/sounds/    with the name as
"meetme-conf-rec-74438-1280463795.8.wav

Than i tried to move the file to /var/lib/asterisk/sounds/conf-recordings/
just to see that it gives me a speaker icon when i click to past
conferences.

Unfortunately i couldnt see this speaker icon to hear this recorded
conference .wav file.

I tried to download the .wav file into my windows machine and the filed
played well..

like i mentioned in my earlier mail that following line i had added in
lib/define.php, please correct me if i am wrong:


define ("RECORDING_PATH",
"/var/lib/asterisk/sounds/conf-recordings/");

Do you think This recording path is taking the effect here?

I am not surprised.  By default MeetMe creates unique file names by appending
pin-uniqueid, but uniqueid is not know until the conference starts, so the web
interface
does not know what to look for.  Part of the changes to app_meetme included
setting the
realtime filename to use.

That setting effect where the WMM interface looks for recordings and not where
Asterisk puts
them.  Looking back at your email history, I see you are on 4.0.1.  After all of
the suggestions,
I remembered that I too found problems with recordings and addressed them in
4.0.2

That version adds a field to the database and stores the recording names in the
database.  I
recommend using that version instead of 4.0.1.  You can move your copy of
lib/defines.php to
the 4.0.2 install and keep your changes.

Dan

Hi Dan,

There was on very silly mistake and i missed to check that properly. Really
apologize for that.
Following change was done to get the conf-recording into the proper path:

chown -R asterisk:asterisk /var/lib/asterisk/sounds/conf-recordings

following is the output:

[root at LinuxTest sounds]# ll
total 6416
drwxrwxr-x  2 asterisk asterisk    4096 Jul 30 08:29 conf-recordings
[root at LinuxTest sounds]# ll conf-recordings/
total 4060
-rw-r--r-- 1 asterisk asterisk 4150124 Jul 30 08:27
meetme-conf-rec-74438-1280463795.8.wav

The only thing now is no speaker icon onto the webpage when i click to past
conference link.

Do you say that if i shift from 4.0.1 to 4.0.2 will fix the issue (of
getting speaker icon in past conference)?

The web interface cannot find the recording.  The reason it cannot is that
the name is wrong.  By wrong, I mean it contains information that the database
and program is not aware of (1280463795.8).  To make this clear, if this
conference was
the 3rd one you ever scheduled on this system the correct file name would be-
meetme-conf-rec-74438-3.wav using the format meetme-conf-rec-%PIN%-%BOOKID%.wav
The database knows the pin and bookid, so it can construct the file name and
test if it
exists.


> Do you say that if i shift from 4.0.1 to 4.0.2 will fix the issue (of

I was not able to get the change into app_meetme to use the bookid in the
filename,
even though it has access to bookid.  I gave up and now store the filename in
the database, which app_meetme will use if it exists.

Other that a handful of bug-fixes, this is the major difference between 4.0.1
and 4.0.2
