Are your interrupts getting hogged by anything else? I'd recommend
http://www.voip-info.org/wiki/view/Asterisk+PCI+bus+Troubleshooting if
you haven't already read it. Have you tried booting with noapic kernel
option? You may then have to shuffle cards around to make your sangoma
not share any interrupts <shrug> hth :)

Hi, I have a trivial setup on a 2.4GHz Xeon Dell PE 1750 SCSI machine
dealing with 4 ports of E1 in an 'inline PBX' arrangement.
My extensions.conf is simply:
[general]
static=yes
writeprotect=yes
[frompstn]
exten => _31.,1,Dial(Zap/g2/${EXTEN})
exten => _31.,2,Congestion
[fromaxxess]
exten => _13.,1,Dial(SIP/${EXTEN},,h)
exten => _13.,2,Congestion
exten => _31.,1,Dial(Zap/g2/${EXTEN})
exten => _31.,2,Congestion
include => outbound
[outbound]
exten => _X.,1,Dial(Zap/g1/${EXTEN})
exten => _X.,2,Congestion
We have a full 30-channel PRI and a 4-channel partial PRI and are
experiencing load spikes that I can't find the source of.
The machine Debian sarge on the default 2.6.8-2-686 kernel, and no other
daemons are running than sshd.
The machine is doing no IP work - purely TDM, yet on a Xeon 2.4GHz
machine, the load average is sitting at 0.6 with 40 active Zap channels
(i.e. 20 live calls) and will randomly jump to 2 (with call quality
starting to stutter)
A few seconds of vmstat:

Does this sound about normal for what is just shuffling data between
ports of the Sangoma A104? I want to record the call data with the
'Monitor' application but this just causes the load to increase even
more (even though 'hdparm' shows 70MB/sec disk transfer with low
user+system CPU usage)
/proc/interrupts is

Help! :)
