I m try to edit file gc_thresh1,2,3 in /proc/sys/net/ipv4/neigh/default/gc_thresh1 but giving error ;file in use.

now i got success by edit # vi /etc/rc.local
                                    echo 1024 > /proc/sys/net/ipv4/neigh/default/gc_thresh1
                                    echo 4096 > /proc/sys/net/ipv4/neigh/default/gc_thresh2
                                    echo 8192 > /proc/sys/net/ipv4/neigh/default/gc_thresh3
                                    # ./rc.local

Rather running this commands by rc.local file it should be added in /etc/sysctl.conf. Just add following lines as per your requirement in /etc/sysctl.conf.

net.ipv4.neigh.default.gc_thresh1 = 1024
net.ipv4.neigh.default.gc_thresh2 = 4096
net.ipv4.neigh.default.gc_thresh3 = 8192

Then  run command "sysctl -p ". This will apply all settings to the above files on runtime. Even when you reboot the machine you will find the same settings.

Hope your problem resolve by this steps. Best of Luck.
