[Asterisk-Users] Avoiding initial deadlock on iax?

[stevanus]

Hi,

My asterisk sometimes stop responding to iax calls.

In the log, I've found this:

Mar 29 13:35:45 DEBUG[8386] channel.c: Avoiding initial deadlock for 
'IAX2/trunkjstpcn-3'
Mar 29 13:35:45 DEBUG[13002] chan_sip.c: update_call_counter(1409) -

'0x81d9530', 10 retries!

It happens unpredictably and all I can do just killall -9 asterisk :S.

When I execute iax2 show channels on CLI, I got messages that indicate 
many iax channel hung and I cannot do soft hangup to them :(.

Here is my iax.conf:

[general]
bindport = 4569           ; Port to bind to (IAX is 4569)
bindaddr = 0.0.0.0    ; Address to bind to (all addresses on machine)
tos=0x68 ;
bandwidth=low
jitterbuffer=yes
dropcount=2
disallow=all
allow=ilbc
;allow=g723.1
;allow=g729
;allow=ulaw
;allow=alaw
;allow=gsm
mailboxdetail=yes
....
the other settings on iax.conf are just iax2 account for trunk and 
personal use. So I cut them in order to save spaces...

Perhaps it's a bug?

I've found this http://bugs.digium.com/view.php?id=4045 ,  but from the 
link I read that it is just for H323 not for iax. Will that patch cure 
my asterisk problem since the symptom are the same?

Anyone has any ideas?

Thanks

Regards,

Stevanus
