[TriLUG] No buffer space

We've got a 3com 3c905 (PCI) NIC running on a RedHat 7.2 box and while
scanning our entire campus subnets (just an Nmap Ping sweep to begin
with) and we keep getting these errors:

sendto in send_ip_raw: sendto(4, packet, 28, 0, 152.2.9.105, 16) => No
buffer space available
Sleeping 15 seconds then retrying
sendto in send_ip_raw: sendto(4, packet, 28, 0, 152.2.9.105, 16) => No
buffer space available
Sleeping 60 seconds then retrying

Can anyone explain this, and is there a way to avoid these errors?  I
imagine it's something with the kernel.

Thanks so much!
Jeff
