Do you use a large subnet mask? For example /16 or /8 or
something like that?

If so, you will need to bump up the neighbour table garbage
collection thresholds under /proc/sys/net/ipv4/neight/default/
Specifically gc_thresh1, gc_thresh2, and gc_thresh3

You probably have a huge number of machines on your subnet.

echo 1024 > /proc/sys/net/ipv4/neigh/default/gc_thresh1
echo 2048 > /proc/sys/net/ipv4/neigh/default/gc_thresh2
echo 4096 > /proc/sys/net/ipv4/neigh/default/gc_thresh3
