[asterisk-dev] [#13935] ast_waitfor_nandfds - channels stuck

[Marcin J. Kowalczyk]

Hi,

 I've found some issue with hanging connections inside asterisk:

<cut>Hi,

I have very strange problem, that some calls remain in my asterisk box. 
I use sesion timer so call should be dropped after expire time but it stays.

My main (I call it Asterisk-IBM) asterisk is 1.6.0.1 stable. Agents also 
use same asterisk version. Each agent has installed asterisk on his PC.

On Asterisk-IBM I can see hanging calls ie:

asterisk-IBM*CLI> core show channel SIP/1127-afccc138

when I login to agetnt's asterisk there is no call
CC1127*CLI> core show channels
Channel Location State Application(Data)
0 active channels
0 active calls
584 calls processed
CC1127*CLI>

In Agent's CDR I can see that call had status "no answer"

CC1127:/var/log/asterisk/cdr-custom# grep 01070403000508505223 *
"","","konsultant","default","Dial","SIP/1127/01070403000508505223","2008-11-19 
20:22:56","","2008-11-19 20:22:57","1","0","NO 
ANSWER","DOCUMENTATION","","","1227122576.1055","","","","","","Local/konsultant at default-28d9;1"
CC1127:/var/log/asterisk/cdr-custom#

For today my Asterisk processed "133053 calls processed" and: 172 active 
channels, 86 active calls hangs in system.


On my "master" Asterisk I have following setup for Session-Timer:
rtptimeout = 600
session-timers=accept
session-expires=120
session-minse=90
session-refresher=uas

rtptimeout=600

on client:
rtptimeout = 600
session-timers=accept
session-expires=120
session-minse=90
session-refresher=uac
</cut>

I've tried to google for ast_waitfor_nandfds but I did not find anything 
interesting.
