Socket:file descriptor exceeds limit (4096/4096)

A DNS server that was managed by a colleague a while ago, because of the number of concurrency, caused a large number of such records in the log:

Socket:file descriptor exceeds limit (4096/4096)

The literal meaning of the error is that you need to provide the number of sockets that can be opened, and you can add the following configuration to the/etc/sysconfig/named:

ULIMIT-HSN 200000options= " -4-s 8096"

Then save, in the restart named:

Service named restart
