Summary:                    getting warning message every 4 seconds
Description: 
I have a 4-span EuroISDN span, with 

https://issues.asterisk.org/view.php?id=1 connected to telecoms provider
https://issues.asterisk.org/view.php?id=2 looped to
https://issues.asterisk.org/view.php?id=3
https://issues.asterisk.org/view.php?id=3 looped to
https://issues.asterisk.org/view.php?id=2
https://issues.asterisk.org/view.php?id=4 unplugged

Upgraded libpri and zaptel to latest versions 

zaptel: URL: http://svn.digium.com/svn/zaptel/branches/1.4 Revision: 4696
libpri: URL: http://svn.digium.com/svn/libpri/branches/1.4 Revision: 1684

before this upgrade, I was getting _no_ warning messages, now I am getting
a
 
"WARNING[2659]: chan_dahdi.c:2790 pri_find_dchan: No D-channels available!
 Using Primary channel 109 as D-channel anyway!"

message every 4 seconds

If I remove the definition of the 4th span from zapata.conf, the message
goes away

I'm in the UK.  I know that some UK telco's do, indeed, drop layer 1 in to
power save - but not on my test rig.  I have it connected to a genuine
ISDN2e, a S0 bus off another switch (Siemens Hi-path that doesn't drop L1)
and a Trend tester (that drops nothing).

So, in my configuration - my layer 1 is always on.  

Just to repeat - libpri v1.4.10.1 and 1.4.10.2 don't seem to have this
problem - it only appeared from 1.4.11 onwards.

I only wish I knew enough about C to help out with the programming...
