[Asterisk-Users] HDLC errors on PRI

[Jason Walker]

I have looked through other postings to the user group for HDLC errors, went
through what worked for other people, and still can not seem to get past
this issue.
 
For 3 days, I have been getting HDLC abort(6) errors in *. Prior to Tuesday,
the circuits were clean...I had maybe 10 HDLC abort messages since August
10th.
 
Here are my specs:
 
 
1 Gig IBM x300 w/ 1 Gig Ram
1 Quad TE405P card
No errors on IRQs
IRQs are separated with NO sharing
hdparm for irq and dma are set to 'on'
 
Software - 
 
FC1 with -1 updates to kernel, etc.
Asterisk v 1.0.9, libpri 1.0.9, zaptel 1.0.9.2
 
1 T1 is a tieline to our Nortel Meridian
3 T1s are a PRI trunk group with D chans on 24 and 48. The third T1 only has
b channels.
 
No alarms from zttool. 
 
Calls go through, inbound and outbound.
 
About every 5 seconds, I get the following on the console:
Nov  4 21:10:37 NOTICE[9693]: PRI got event: Alarm (4) on Secondary
D-channel of span 1
Nov  4 21:10:37 NOTICE[9693]: PRI got event: HDLC Abort (6) on Primary
D-channel of span 1
 
The errors seem to increase as calls come in and out. There is also a
noticable "popping" when the error happens.
 
Any suggestions are welcome.
 
thank you
 
Jason
