[Asterisk-Dev] Chan_capi 0.3.1 , Asterisk , 3 x C4 active ISDN card Segmentation fault

[Sascha]

Hi,

i use chan_capi 0.3.1 with asterisk (stable branch cvs)  and 3 x c4 
active ISDN card.

 From Controller 1 - 7 there are no problems making calls between 
asterisk and the pstn.

But when i make calls from controller 8 - 12 i get on every controller 
(8 - 12) a segmentation fault in asterisk :(

I tried different linux distributions (gentoo 2004.1, redhat 9.0 , suse 
9.1) but same error.

Example :

I call the number on the 8 controller (9766)  ->  there i have a  
playback -> serverproblem.gsm

when i hang up i get the segmentation fault:



/usr/sbin/asterisk -vvvvvvvvvvdc with gdb

Is chan_capi limited to 1 x C4 ?



Thanks for your help.


Kind regards
