Sounds like an arp table overflow; this means you either have a *LOT* of hosts attached to your network, or some weird routing going on.
If you are sure that you don't have routing loops or other strange routing-stuff going on, and suspect you have more than a couple of hundred Ethernet devices connecting to these machines, try one of the following:
1) Switch to using arpd (IIRC you need to set this option when compiling your kernel, and then start the userspace arpd which is apt-gettable)
2) Increase the values in /proc/sys//net/ipv4/neigh/default/gc-thresh[1-3]
If you choose the second option, don't forget to add these to /etc/sysctl.conf so the settings will be restored on the next reboot.
