asterisk users - Feb 2012 - asterisk dahdi problem.

Hi all,
I was using dahdi 1.6.2.0.9 version for a long time.
We decided to upgrade to 1.6.2.22 a few days ago.
After that we started to have some problems with dahdi channels.
PS:DAHDI Version: 2.6.0 Echo Canceller: HWEC, MG2


We have 2 PRIs between Ericsson pbx and asterisk and a sip trunk for
outside calls.

At begining everything works fine but in a few hours, calls from asterisk
to ericsson stops with
app_dial.c:1780 dial_exec_full: Unable to create channel of type 'DAHDI'
(cause 0 - Unknown)


 My call rules are as DAHDI/g1/
Even i restart dahdi or asterisk, i keep on getting the same error. But
meanwhile calls from ericsson to asterisk works fine. WHen i replace
DAHDI/g1 as DAHDI/1, it starts to work again.

Is there a problem with g?? Is it a known problem?
What might be the solution??

Thank you.



PS: While i was monitoring it started to give same error with dahdi/1
config too.

I got no alarm on dahdi channels or ericsson side.
dahdi show channels are

      4            DID_span_1                 default                     
   In Service

core show calls
12 active calls

Is there a number missing here?

Do you actually have dahdi channels marked with group=1 ?

Can you provide your chan_dahdi.conf with ever file #include-d into it?
