I am having a little problem.
4 active PRIs with independent D-channels, total available b-channels 92.
When I send more then 92 calls via sip peer the PRIs crash one by one disconnecting all the connected channels and not allowing new call connect.
The expected respond should be busy/channel unavailable but instead the PRI (d-channel) crashes
I am including my config:
/etc/dahdi/system.conf
span=1,0,0,esf,b8zs
span=2,0,0,esf,b8zs
span=3,0,0,esf,b8zs
span=4,0,0,esf,b8zs
bchan=1-23,25-47,49-71,73-95
dchan=24,48,72,96
loadzone = us
defaultzone=us
I get same result with 1,1,0 2,2,0 3,3,0 4,4,0 and 1,1,0 2,1,0 3,1,0 4,1,0

After over a week of hair pulling I wish to ask for any suggestions.
dmesg and messages log does not show any related errors. Also there is no IRQ conflict.
