Linux uses this mechanism to throttle the spamming of log events, decreasing the likelihood of a denial-of-service attack.

You can find tune this feature by amending two settings net.core.message_burst and net.core.message_cost .

These parameters are used to limit the warning messages written to the kernel log from the networking code. They enforce a rate limit to make a denial-of-service attack impossible. A higher message_cost factor, results in fewer messages that will be written. Message_burst controls when messages will be dropped. The default settings limit warning messages to one every five seconds.

To check their current values use:

sudo sysctl -a | grep net.core.message_

To amend them:

sysctl -w net.core.message_cost=0

Please note that disabling this mechanism is not recommend in production environments.
