Besides the normal cache Timeout there are multiple strategies to detect
dead neighbours, for example for fall back gateways and quicker usermode
notification.

It might help to set gc_stale_time higher, set locktime higher,
or set ucast_solicit and mcast_solicit to 0.

2ecki@calista:/proc/sys/net/ipv4/neigh/eth0> egrep . *
anycast_delay:100
app_solicit:0
base_reachable_time:30
delay_first_probe_time:5
gc_stale_time:60
locktime:100
mcast_solicit:3
proxy_delay:80
proxy_qlen:64
retrans_time:100
ucast_solicit:3
unres_qlen:3

See for example
