It looks like you have only 3 lines in your arp table, so it's really hard to understand how it would overflow from that.
What does the output of "arp -a" look like?
You can also look at: cat /proc/net/arp
Please post the output of: sysctl -a | grep neigh
Do you have IPv6 enabled?

Hi Filipe,
The output from sysctl -a | grep neigh is:
