The W1 "receive" buffer full message is telling you that it isn't the
ethernet.

Possibly. Do you have filters? OSPF? SNMP? RIP?

Corrupted packet. Probably when the receive buffer fills up, a packet
is destroyed.

Turning off LCP echo-requests will reduce load a bit. PPP LCP
echo-requests are of a dubious value on many connections.

Again corrupted packet. Sometimes this kind of stuff "just happens".
