[asterisk-users] Asterisk 11 on Centos: Voicemail crashes when recording message

[asterisk]

Hi folks,

I'm running Asterisk 11 (at the moment - planning to u/grade to v13.7 
LTS), I've just configured the voicemail function, and it's mostly 
working fine... except when I try to leave a voicemail! This crashes 
asterisk with no entries in the messages log.

The system is running on Centos 6 (or maybe 6.5, I'm not sure how to 
check this). uname -a returns:

     Linux asterisk.sjssolutions.local 3.10.0-327.13.1.el7.x86_64 #1 SMP 
Thu Mar 31 16:04:38 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

On the CLI, I get this:

    asterisk*CLI>
    Disconnected from Asterisk server

(note: Yes, it's deliberate that it's going to a different extension 
VM... the call goes via another asterisk server to a remote phone; then 
comes back if unanswered to record the VM.)

The system starts to create the file, and sometimes even records some 
bytes, before dying:

    [root at asterisk tmp]# ls -l
    total 4
    -rw-r--r-- 1 root root  0 May 16 20:38 nzuoKd
    -rw-r--r-- 1 root root 44 May 16 20:38 nzuoKd.wav

Note: I've since changed the safe_asterisk script to start up Asterisk 
as asterisk:asterisk, it seems to still work; apart from VM which 
crashes the same way.

I tried setting the file format to ulaw, this had the same problem 
(except the temp file ended with .ulaw). I saw a similar problem had 
been solved in version 1.6.1, except that didn't seem to show the "x=0, 
open writing:" message.

System has plenty of available disk space (40G or 179G depending on 
which bit of the filesystem you look at).

I've never seen this on any of the Asterisk servers I've run (many, 
since v1.4), but I mostly run it on Ubuntu variants, this is my first 
Centos...

Addendum: I modified safe_asterisk & got the following when it quit:

     /usr/sbin/safe_asterisk: line 163: 18115 Illegal instruction     
(core dumped) nice -n $PRIORITY "${ASTSBINDIR}/asterisk" -f ${CLIARGS} 
${ASTARGS} > /dev/${TTY} 2>&1 < /dev/${TTY}

Any ideas gratefully received. I'm going to try installing a 
compiled-from-source version of 13.7 at the weekend, can't do it before 
then as it's our production office system... Everything apart from VM 
seems to work (although if anyone can shed any light on the frequent 
"res_rtp_asterisk.c:4264 ast_rtp_read: RTP Read too short" warnings I'm 
seeing, that'd also be appreciated.

Oh - one more thing, I had to disable 2 codecs (lpc10 and ilbc) because 
they used an instruction that doesn't exist on the server (it's an 
oldish HP mini-server). I'm guessing from the above message that VM 
might be afflicted by the same issue. Presumably compiling from source 
will solve this? (I've compiled 13.7, no errors reported, but I've not 
tried running it yet)

Cheers!
Ade.
