<![CDATA[2.0RC1 i386 full install : "kernel: arpresolve: can't allocate llinfo for …"]]>I have two SMTP relays behind pfSense.
I get this error VERY repeatedly as soon as I enable WAN load balance for outgoing smtp traffic.
I need to revert to WAN fail-over for the error to vanish.

Connections trying to use the new interface fail and the connections do not work proberly at all (most of them time out).

I use VLAN's for my WAN connections. Each ADSL Router has it's own VLAN and Network (a 10.100.<vlan>.0/28 net) where vlans are counting up from 100. So there is no overlaping.

Another symptom I have is with the failover pfsense box, which when started does not recognize it's Backup and everything is Master, I have to deactivate CARP and activate it again on the Backup-Router to have it become Backup. Then all gateways are offline except the one which is on the interface which gives me the problems described above with llinfo stuff, it stay's online and I get packet loss on both, the primary and the backup box …

The servers are no-name computers with Intel PRO dual-port server network cards.

Hope someone can figure out what's going on, i have this since the Beta through 2.0-RC3 (i386) built on August 3rd.

best,

I'm using 2.0b5, Feb 18th build, i386.
Running on an IBM x345 rack server with 2 built-in Broadcom (em0/1) and 2 Intel Pro/100 NICs.
I'll update to the latest snap tonight, and test again.
Working around the issue currently using policy-based routing (works ok…)
Thanks!

Load balancing with 2 ISPs, the issue only shows up if I enable sticky connections under system>advanced>Misc.
As soon as I check it and save, that message start filling the log, with both my WAN IP addresses alternating
in the log message.  Traffic works about 50/50.  First load of a webpage usually fails, retrying it 1 or two times
gets it to load. 
Difficult to use load-balancing without this, as sticky connections is essential for secure sites such as banking.

Nope, they are from two totally different ISPs.
One is KPN and the other one is Voo (Brutele).
