Recently 1 of the server under my responsibility very slow. The ping is always timeout. When i type “dmesg” it show;
Nov 1 22:23:40 bounty kernel: ip_conntrack: table full, dropping packet.
Nov 1 22:23:43 bounty last message repeated 9 times
I run this command to know how many connection on the server:
[root@svr6 ~]# cat /proc/net/ip_conntrack | wc -l
It can be fixed by restarting the server. After restart, the ping seem ok and no timeout. Run back the command:
[root@svr6 ~]# cat /proc/net/ip_conntrack | wc -l
