How to block kernel arpresolve: flood?

[k625]

I use MultiWan with two interfaces and two ISPs in failover mode. One of the ISP has a feature, from time to time with it the link is interrupted for a few minutes. This situation is easily simulated by simply disconnecting the cable from the network interface.
The problem is that the system log / general, for any size, is filled with messages of this type:

Mar 12 11:07:28 kernel arpresolve: can not allocate llinfo for x.x.x.x on vr0
Mar 12 11:07:29 kernel arpresolve: can not allocate llinfo for x.x.x.x on vr0
Mar 12 11:07:29 kernel arpresolve: can not allocate llinfo for x.x.x.x on vr0
Mar 12 11:07:30 kernel arpresolve: can not allocate llinfo for x.x.x.x on vr0
Mar 12 11:07:30 kernel arpresolve: can not allocate llinfo for x.x.x.x on vr0

This leads to the fact that it is impossible to know when the link was broken and what preceded it.

My question is - can I somehow block this flood?

Thanks.
