I'm not sure if this posting will go to the correct thread or not, as I 
am subscribing to make this post, and don't have a message to reply to. 
Hose, if this does not end up in the thread can you post in in there?

I am getting the same DAHDI error, under Asterisk 1.4.25, libpri-1.4.10 
using a TE420 (TE420P I believe). Only Asterisk does not crash but all 
the channels on the port/group are listed as not busy and no calls get 
received or placed over the span.
It also happened at a time of no use, just after a restart message 
*SHOULD* have appeared in the log for that span, though the span would 
have been nearly 100% busy for more than 8 hours the previous day. I did 
not get a dahdi_test, sorry.

The last messages are repeated over and over. Removing the T1 from the 
port and plugging it back in fixed all the problems(although it was 
plugged into another phone system to test it for 2 minutes).
Asterisk or DAHDI were not restarted.
