[asterisk-users] HDLC Receiver overrun on Wildcard TE410P

[Łukasz Krzyżak]

Hello
I've got small PBX (30 simultaneous connections) based on asterisk
(1.6.2.6), which uses Stargate 2N ISDN to GSM gate.

It runs ok for day or two, but then I get:

dahdi: HDLC Receiver overrun on channel TE4/0/1/16 (master=TE4/0/1/16)

in my kernel logs, in asterisk i get:

pri show spans
PRI span 1/0: Provisioned, Down, Active
PRI span 3/0: Provisioned, In Alarm, Down, Active

(span 3 is not connected to gateway for now)

and I can't make any calls.

My dahdi-channels.conf:

; Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" (MASTER)
group=0,11
context=from-pstn
switchtype = euroisdn
signalling = pri_net
channel => 1-15,17-31
context = default
group = 63

/etc/dahdi/system.conf:

# Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" (MASTER)
span=1,0,0,ccs,hdb3,crc4
# termtype: te
bchan=1-15,17-31
dchan=16
echocanceller=mg2,1-15,17-31

I manually set irq affinity - eth1 to CPU2, digium card to CPU3, rest
of common interrupts to CPU0 and CPU1

PBX runs on HP ProLiant DL380 G5 server, OS is Gentoo Linux with 2.6.31 kernel.

Other software versions:
asterisk - 1.6.2.6
libpri - 1.4.10.2
dahdi - 2.2.0.2

any idea what could be the problem / what should I check to diagnose it ?
