[arm-allstar] Asterisk crashing when Echolink connected

[Matt]

Hi David,

I'll keep it on the list if you don't mind as it may help others if this 
problem comes up again. I have a working theory but I need to do a bit 
more testing to confirm.

Here are these servers listed in my echolink.conf...

server1=servers.echolink.org
server2=naeast.echolink.org
server3=backup.echolink.org

I noticed that the crash happened just after this line in the asterisk 
console..

-- Received OK from Echolink server servers.echolink.org
-- Received OK from Echolink server backup.echolink.org
allstar*CLI>
Disconnected from Asterisk server
Executing last minute cleanups

So, I've changed the servers to the following...

server1=europe.echolink.org
server2=servers.echolink.org
server3=backup.echolink.org

And now it only connects to a single server in the asterisk console...

-- Call changed from OUTBOUND to *ECHOTEST*
-- Name changed from OUTBOUND to (Conference  [9]) CONF
-- Received OK from Echolink server europe.echolink.org
-- Directory pgm done downloading(partial,compressed), 377 records

And have been up for 20 minutes without a crash. Maybe the problem was a 
bad server in the echolink pool?

In answer to your questions.

Is IPv6 networking in this mixture anywhere? - We have an ipv6 tunnel 
set up on our main router but all internal networking is ipv4
What are your Echolink and AllStar node numbers? 43412 (AllStar), 214700 
(Echolink)
Does the crash occur when connecting to all Echolink nodes (like the 
Echolink *ECHOTEST* conference server, node #9999)? Happens on all nodes 
I have tried
Does AllStar connectivity work properly? Yes. I have not seen any 
asterisk crashes when not connected or when connected to an allstar node

My current echolink.conf

[el0]
confmode=no
call=MB7IBK-L        ; Change this!
pwd=pypassword          ; Change this!
name=MB7IBK           ; Change this to your real name!
qth=Broadstairs, UK    ; Change this to your actual QTH!
email=matt at m0lmk.co.uk ; Change this!
maxstns=20
rtcptimeout=10
node=214700               ; Echolink node number - Change this!
recfile=/tmp/recorded.gsm
astnode=43412            ; Change this to your active Allstar node number!
context=radio-secure
server1=europe.echolink.org
server2=servers.echolink.org
server3=backup.echolink.org
;server1=servers.echolink.org
;server2=naeast.echolink.org
;server3=backup.echolink.org
; Change following setting to your parameters
freq=145.2125
tone=103.5
lat=51.36242
lon=1.44442
power=1
height=1
gain=0
dir=0
;deny=
;permit=



Hope that helps.
