[Asterisk-Users] zaptel ppp HDLC Receiver Overrun messages

[Mark Farver]

I have a pair of sites tied together with a T1 line running zaptel PPP
on either end.  The system works, but I keep getting these messages in
the kernel logs, and users are reporting connection problems (TCP
timeouts, and hangs) especially under high usage.

HDLC Receiver overrun on channel WCT1/0/1 (master=WCT1/0/1)

My initial though was interrupts, the LAN was connected via eth0, which
is sharing with the t1xxp card running the WAN link.  (The t4xxp card is
for a future project and is idle) but I downed eth0 and switched the LAN
to eth1.

/proc/interrupts:
           CPU0

 14:      32528          XT-PIC  ide0
 15:      27273          XT-PIC  ide1
NMI:          0

My only other idea is the box is underpowered for the job.  It is a
P3-350 mhz...

Any other suggestions?
