Kernelarpresolve: can't allocate llinfo for After 2.3.3 Upgrade
-
Upgraded my unit this morning to Pfsense version 2.3.3, upon doing so, my management interface became unreachable via SNMP.
Looked in the logfile and seen this error pop up every minute:
kernelarpresolve: can't allocate llinfo for x.x.x.x on bce0
I seen an older post that going into Interfaces > (my management interface) and click Save and Apply may rectify the issue.
The management interface now is no longer reachable and does not ARP.

That message usually means it's trying to contact something on that interface that isn't actually on that interface. For example if the interface subnet is y.y.y.0/24, but it's trying to find x.x.x.x on that interface using ARP.
You need to look at the interface configuration, interface status ("ifconfig -a" output is preferable) and compare it to what you see in the routing table (Diag > Routes, or "netstat -rWn") and see if it has a proper link route.
You might see that in some cases if an address was on an interface and then disappeared.
Resetting states for that address might also help.
