I think you mean 64k packets? If so, the network is fragmenting your large packets, likely into 1500 byte packets. This would be fine unless;
1) You are using Frame Relay and packets are being dropped.
2) You have a full/half duplex mismatch somewhere between a device and a switch.
3) You have an overloaded network and packets are being lost from buffer overflows and/or collisions.
4) You have a defective network interface device or cable damaging packets. Or the network is out of spec, such as running a cable farther than it is made for.
Every packet is kept open until they are complete. If you have a 10% packet loss, and each Large Internet Packet (LIP) is being divided into 6 parts, then every other packet must remain open until it is NAK'd and retransmitted.
When you do ifconfig, are you seeing errors in the interface statistics?
