Ethernet stops communicating, ARP cache full of incompletes

I have a Ubuntu 10.04.5 LTS, system on a AMD 64bit system with 16GB. Recent Zoneminder install has cranked up traffic. But I did not use this system prior.

After a while (minutes to hours), the system stops communicating. When this happens, the ARP cache is full on incompletes, and the only way to reset is to reboot or unplug the Ethernet. Eventually it happens again. I have tried 3 different drivers up to and including the latest from Realtek. No real diff between them. Currently using the r8168, 8.045.08, 4.15.0-118-generic, x86_64 driver per dkms.

Any ideas why it keeps dropping?
