Description:If I enable email notification of voicemail messages, asterisk crashes.  Does not matter if I attach the message or not.  

I have a core dump, which I can give to you also.  Please let me know if I can provide additional info.

****** STEPS TO REPRODUCE ******

create voicemail configuration with these entries:


[general]
format = wav49|gsm|wav
serveremail = asterisk@a2pg.com
skipms = 3000
maxsilence = 10
silencethreshold = 128
maxlogins = 3
pagerfromstring=A2PG Asterisk PBX
emaildateformat= %A, %B %d, %Y at %r
tz = eastern
attach = no    ;; doesnt matter if this is no or yes
saycid = no
sendvoicemail = yes  
delete = no
nextaftercmd = yes
forcename = yes

[zonemessages]
eastern = America/New_York|'vm-received' Q 'digits/at' IMp

[a2pg-staff]

Can you provide a bt full?
By: brook davis (mrgoby) 2007-11-12 12:35:21.000-0600

do i need to rebuild asterisk with debugging symbols to do that ?   I get the following when doing a bt in gdb:

Yes, you do.  Also, please follow the instructions in doc/valgrind.txt.
By: brook davis (mrgoby) 2007-11-12 13:34:31.000-0600

I'll need to coordinate with my customer who is running this system in production.

I notice the docs/valgrind.txt does not exist in my stable source directory, but does in an SVN co.

For some reason I can't run 'make menuselect' in my stable source (it complains about ncurses missing, even though it isn't), but I can run it in my svn co, after copying $AST_SOURCE/makeopts to $AST_SOURCE/menuselect/makeopts.

Should I just checkout the 2.6.12 branch head and build that?  Or, what would you suggest ?   Is menuselect supposed to run in the stable releases?
By: Tilghman Lesher (tilghman) 2007-11-12 15:04:47.000-0600

There is no 2.6.12.  Perhaps you meant 1.4?
By: brook davis (mrgoby) 2007-11-12 15:22:21.000-0600

yes...  1.4.12 is what I am using in prod to produce the issue...  sorry for confusion...
By: Tilghman Lesher (tilghman) 2007-11-12 16:25:11.000-0600

Yes, please run the latest 1.4.  In terms of menuselect, please try running 'make -C menuselect clean' and retry.  Menuselect sometimes doesn't re-run its own configure when it needs to.
By: Tilghman Lesher (tilghman) 2007-11-14 18:02:49.000-0600

Really need valgrind output to find the issue.
By: brook davis (mrgoby) 2007-11-15 09:54:58.000-0600

Coordinating with client now, will try to schedule downtime with him today to capture output.
By: brook davis (mrgoby) 2007-11-15 11:58:19.000-0600

Okay, an interesting development...   I followed the instructions in valgrind.txt with the same source 1.4.12.  I finally got menuselect to work by editing menuselect/makeopts and pointing it at ncurses manually (this seems broken to me, but maybe not).  Anyway...  

At first, I was concerned because the segfault doesn't occur, but my colleague informs me this is to be expected... posting valgrind output momentarily

valgrind.txt attached...   malloc_debug.txt was empty, so omitted.

I'm getting the exact same problem. I just upgraded my kernel to 2.6.23.1-21.fc7 and the problem persists. If I don't send an email notification then asterisk if fine. If I do then the following occurs:

Disconnected from Asterisk server
Executing last minute cleanups
Asterisk ending (0).

Asterisk ended with exit status 139

dmesg output:

The voicemail still get's emailed which is strange.
I'm running asterisk 1.4.14

I've been having other problems with FC7 kernels lately.  I'm going to try a vanilla Linus kernel and see if that resolves the issue.   Will report back...
By: Tilghman Lesher (tilghman) 2007-12-14 09:30:21.000-0600

Okay, this valgrind.txt doesn't actually contain a memory free'ing error.  Could you try this again?
By: Tilghman Lesher (tilghman) 2007-12-27 17:41:40.000-0600

No response from reporter.  Reopen (or ask a bug marshal to) if this is still an issue.
