Versions:1.8.4 Frequency of
Description:The system works fine but after a few hours or a few days, it's impossible to send or receive calls thru DAHDI with a Digium BRI card (two different platform using HA8 and HB8) using :
- Asterisk 1.8.x
- LibPRI 1.4.11.x or 1.4.12-betax
- DAHDI or dahdi

On same platforms, no problem :
- if not using BRI
- using BRI with the following configuration : Asterisk-, LibPRI and DAHDI

Some debugging information would be very helpful to figure out what is happening.

Have you tried 1.8 SVN?  There has been a large fix in this area dealing with B channel shifting during call negotiation.

Which debugging information would you like and how to get it ?

I've already tried 1.8 SVN. The problem still occurs.

Note: there is a lot of IRQ misses on platforms concerned using 1.8.x versions.

1) A CLI capture of output during a call attempt. (verbose level 4 or greater)
2) The chan_dahdi.conf file.
3) Possible libpri debug output capture. (pri set debug on span x)

Also try the libpri SVN 1.4 branch.  There is an I-frame retransmission fix made since 1.4.12-beta3 that may apply here.

Suspending, lack of feedback from reporter.
