Gnu/Linux servers (when used extensively as a server) throw the following messages in log file
kernel: Neighbour table overflow. 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 |
