Hello all.
I am seeing the issue below:
kernel arpresolve: can't allocate llinfo for x.x.x.x on em0
The only way to resolve this issue is to bump the interface, or perform
any other task in the GUI that reloads fundamental components of the
interface.
I've found the below links that speak to the problem, but offer no real
solution:

https://forum.pfsense.org/index.php/topic,62964.0.html
System is running pfSense 2.3.1.
The issue is affecting only one of the two interfaces. The em1 interface
is Internet-facing, while the em0 interface is on a private network.
I also confirm that this issue affects only IPv4. IPv6 on em0 is not
affected, and IPv6 traffic continues to flow fine after the IPv4 traffic
stops. I suppose it fits with the kernel error, since IPv6 uses ND in
lieu of ARP.
Does anyone know what this really is?
All help appreciated.
Mark.
