Perhaps, but these data should not get anywhere near the code that
prints out this message. The code that generates that message is
the one that parses the output from "netstat -s" which should look like

Ip:
    3017099 total packets received
    1 with invalid addresses
    0 forwarded
    0 incoming packets discarded
    3017058 incoming packets delivered
    3154813 requests sent out
Icmp:
    51081 ICMP messages received
    0 input ICMP message failed.

What does this command report on your host?

Henrik
