Dnsmasq: failed to send packet: No buffer space available

Hello everyone,

I'm running a network with about 90 clients behind a pfSense box + captive portal + snort (pfSense 2.0.3 amd64 + Celeron G1610 + 4GB RAM + 2 x Intel PWLA8391GTLBLK NICs) and my system log is inundated with messages like these:

…
May 20 17:32:23 kernel: arpresolve: can't allocate llinfo for ...193
May 20 17:32:23 kernel: arpresolve: can't allocate llinfo for ...193

..*.193 is my gateway.

Everything seems to be working fine for now, but still, i there anything I should be worried about?
Is there any way to suppress these messages?

Thank you.
