if i install asterisk 1.4 (yum -y install asterisk asterisk-configs asterisk-voicemail asterisk-addons-mysql)
this does not occur

If i install asterisk 1.8 (yum -y install asterisk18 asterisk18-configs asterisk18-voicemail asterisk18-addons-mysql)
this issue does not occur

only when i install asterisk 1.6 (yum -y install asterisk16 asterisk16-configs asterisk16-voicemail asterisk16-addons-mysql)
Issue occurs.

I compiled 1.6.2.19 from source and the issue does not occur. It *appears* to be only the provided binary.
By: Byron Smith (byronsmith) 2011-07-11 08:57:10.504-0500

I was able to reproduce this issue on 1.6.2.19 compiled from source.

The process would core dump after a few reloads so not every time.

Please let me know if there is anything I can provide to help with the investigation.

FYI, I'm not running FreePBX, this is plan old Asterisk and I would issue multiple reloads from the CLI for this dump to occur.

Per the Asterisk maintenance timeline page at http://www.asterisk.org/asterisk-versions maintenance (bug) support for the 1.4 and 1.6.x branches has ended. For continued maintenance support please move to the 1.8 branch which is a long term support (LTS) branch. For more information about branch support, please see https://wiki.asterisk.org/wiki/display/AST/Asterisk+Versions


By: Leif Madsen (lmadsen) 2011-07-11 15:06:37.966-0500

Closing based on feedback that this does not happen with Asterisk 1.8.
By: Vladimir Mikhelson (vmikhelson) 2011-07-18 10:17:29.518-0500

FYI.

Similar if not the same behavior still observed as of 1.8.5.0 with FreePBX.

See https://issues.asterisk.org/jira/browse/ASTERISK-17498

This is a bt from a user at FreePBX forums running into the issue.
By: Mikael Carlsson (mickecarlsson) 2011-07-18 13:00:19.814-0500

This is from another user, same issue, same core
By: Mikael Carlsson (mickecarlsson) 2011-07-19 03:21:42.506-0500

As per advice to one of the users to install 1.6.2.18 and test it I can now confirm that 1.6.2.18 work as it should. So this is clearly a regression between 1.6.2.18 and 1.6.2.19. This ticket should be reopened.
By: leearcher (leearcher) 2011-07-20 06:00:53.375-0500

I agree, this ticket needs to be reopened as I have had this with 1.6.2.19.
By: Malcolm Davenport (mdavenport) 2011-07-20 10:57:01.474-0500

Re-opening per statement here:
http://lists.digium.com/pipermail/asterisk-users/2011-July/264758.html

Segfault can be produced with stock 1.6.2.19, compiled from source, using stock configuration files, built from 'make samples,' simply by typing "reload" from the Asterisk CLI.

By: Kinnith Wallace (kwallace) 2011-07-22 11:49:28.911-0500

It appears that the issue Summary should be, "asterisk 1.6.2.19 core dump on reload".  (Remove "{{from freeepbx}}", based on preceding comment by [~mdavenport].)

[~808blogger] (or someone else who notices and has permissions to do so), could you edit it?

I see the same issue with 1.6.2.19 on AstLinux (crosscompiled with buildroot) on a Soekris 5501 after exactly 2 reloads:

First reload:
Jul 31 14:00:53 pbx5501 local0.notice asterisk[26090]: NOTICE[26723]: app_queue.c:5673 in reload_queue_rules: queuerules.conf has not changed since it was last loaded. Not taking any action.

Second reload:
Jul 31 14:01:07 pbx5501 user.info kernel: asterisk[25975]: segfault at 6b726174 ip 080cb319 sp bc9fd5a0 error 4 in asterisk[8048000+13f000]
Jul 31 14:01:08 pbx5501 user.info safe_asterisk: Asterisk exited on signal 99.

For whoever picks this up:

I ran through some revisions to test, and I believe r313047 is causing this.

Edit: and when I say "I believe", I actually mean "am 100% certain".
By: Jonathan Rose (jrose) 2011-08-01 15:56:08.649-0500

Patch that should probably fix the bug and I don't think will break anything else in the process.
By: Jonathan Rose (jrose) 2011-08-01 15:57:29.959-0500

Alrighty, sorry for breaking parking in 1.6.2.  I've posted a patch which should hopefully fix the issue if any of you would be so kind as to test it for me.  It worked on my box.

Also, here is a link to the review board page for anyone who wants to review the patch:
