I have 3 private dedicated server as Load balancer. And then there is IP Addr Public sign to this private dedicated server.
Suddenly, one of these 3 LB servers got nf_conntrack: table full, dropping packet
My dedicated server spec is 32 Core; 256 GB. I read some nf_conntrack and finally i am planning to increase the conntrack_max to about 4 millions. But i need a more recommendation from you all who have experience and expert in Server Performance.
When do we need conntrack ? Meanwhile, this is dedicated server with private ip not a NAT gateway. Should i remove conntrack ?
