asterisk users - Dec 2009 - Sangoma card reports HDLC errors

Hello,

I've recently bought a new Sangoma A104d PCI-card.
WANPIPE release is 3.4.7.
Machine is a dual Xeon with Debian 5.0.3.
Asterisk is 1.6.11 with recent libpri and dahdi.

When I boot the machine (including hardware and wanpipe
and dahdi drivers) and start asterisk, everthing runs
fine for almost 5 minutes.

Then every few seconds HDLC errors occour.

I also tried booting - and starting asterisk later: The
HDLC errors start almost 5 minutes after booting (not
after starting asterisk).

I cannot find any other job, starting after almost 5 minutes
and consuming resources, top also show almost 100% idle time.

I also tried to produce high load during the first 4 minutes,
tar.gzing large directories. Anyway, no HDLC errors during
the first 4 minutes, just after almost 5 minutes.

For me, it seems, that there is anything within the sangoma
drivers or the dahdi software overrunnig after appprox 4 minutes
and 50 seconds, causing those HDLC errors.

Any idea, who to find the cause of the error or how to solve
it?

Hi,

mea maxima culpa.

I've found the cause, however Sangoma card and driver
are working excellent.

Just for the archive, to help someone else, maybe having the
same problem:

In order to test my system before bringing it to the data
center, I plugged in a loop cable. Therefore I had to
switch the E1 clock mode to "master" instead of "normal".

Of course I knew, I have to switch it back to "normal", before
connecting to the real carrier, but I forgot.

Anyway, the dependence of the 4:50 minutes remains funny.
Maybe a function of the divergence of the two clocks (my
one the the carrier's one).


Thank you answering anyway!

Roger.
