The solution to the problem is to increase the threshold level for the network devices!
To check the present threshold level 1:
cat /proc/sys/net/ipv4/neigh/default/gc_thresh1
It will give some value as 128 or 256 or 512.
This can be increased to the next level.Like if the value is 128 then make the thresh1
value as 256 and thresh2 as 512 and thresh3 as 1024.

echo 256 > /proc/sys/net/ipv4/neigh/default/gc_thresh1
echo 512 > /proc/sys/net/ipv4/neigh/default/gc_thresh2
echo 1024 > /proc/sys/net/ipv4/neigh/default/gc_thresh3
This will stop the Error messages that were recieved in the log file
