I see event 6 on one of ours all the time. It seems to come along
several times a minute sometimes. I have never known quite what it
meant. It never seemed to affect operation, as the circuit works great
and sounds fine.
FWIW, it is a PRI circuit between * and a Merlin Magix, with *
providing network side signalling.

I've found in testing that events 6 and 8 seem to be related to high call
setup load on the PRI.
In a loop-back load test, I get lots of these when running more than 30
outbound channels looped to 30 inbound on the same box, in an IVR-only test
with no transcoding. Doesn't seem to matter, in my testing, how powerful
the processor is - they still occur at a wildly varying rate.
These particular events, along with the more-common frame retransmission
errors, do not seem to cause big problems by themselves.

Ours will be completely idle and get this as well. However, as near as
I can tell, it does not affect it in any way, besides being annoying
on the console. If I remember correctly (it has been a while) if I
unplugged the circuit and waiting about 30 seconds, plugged it back
in, the messages reduced in frequency.
The searching I did lead me to believe the message was no big deal,
and the last 3 months of it working fine has also told me that it is
probably no big deal. It has been one of my most stable systems out
there.

Is there any way we can disable this message from coming out on the
console so that Asterisk 'filters' these event 6 and 8 messages?
Sometimes it can get quite annoying especially when trying to look at
the CLI. :)

I use digium E100 card with EUROISDN switch type. I have got 6 and 8
messages too.
Inbound call from PRI to Asterisk has no problem. But outbound call to Zap
channels always get the error message as follows,
---------------------------------------
Unable to create channel of type 'Zap'
== Everyone is busy/congested at this time
---------------------------------------

Is this normal? I would think not.
Hi Brian,
seems to depend what sort of switch the Asterisk node is connected to
and over what sort of connection.
You will see occasional transmission hits if you are connected to a
Nortel DMS when the REX (Routine EXercises) are running and the D
channel is switched from X to Y (or the reverse) but that would
account for a hit every 2/3 weeks depending on the size of the switch
and the REX schedule (usually after 01:30 when everything is quiet).
The same kind of effect can be observed on Marconi System X switches
using SS7 signalling when change overs occurr, sometimes twice a day,
not pleasant stuff to watch all the GLKs bounce...
Apart from switch change overs the production systems in our customers
show very few event 6/8 messages unless cabling is dodgy (one
co-located server suffered this problem when the Telco had a poorly
patched connection on the frame). Systems that have been running since
the beginning of this year show less than 1/2 dozen events after the
initial cabling has been proven.
Something similar was noted with the new SS7 stack for Asterisk when
the load was high and although the initial suspicion was related to
interrupt priorities I believe that the solution was found in
software.
