Try:
netstat -s | head -25 | tail -2
... and tell us if you see anything different from:
0 discarded for bad checksums
0 discarded for bad header offset fields
It's possible that the problem is that you have bad hardware
checdksum hardware in the senders, and the packets are being
dropped intentionally because of this.
It could also be that the reassembly buffers are not being
mixed... which still means you need to look at the wire
contents again.
