asterisk users - Nov 2005 - PRI HDLC abort on dchan

I used sftp to move the RC2 files to my * server.  During the whole time 
of the transfer, asterisk continuously reported:

Nov 15 20:09:15 NOTICE[27290]: chan_zap.c:7395 pri_dchannel: PRI got 
event: HDLC Abort (6) on Primary D-channel of span 1

I ran top during that time, and there was no significant cpu usage.

The system uses Asterisk 1.0.7.  The cpu is an Opteron on a Tyan 
motherboard.

Can anyone explain this?

Probably interrupt starvation... are there any interrupts being shared, 
or does your NIC driver take an especially long time to handle interrupts?
