Default dhcpd:No Buffer space avaible

Hi everyone!

In my logs i have following messages:

dhcpd: send_packet: No buffer space available

Server is running at openbsd 4.3 and offering such services like: pf+queing(3 interface, altq+hfsc on each one), DHCPD, DNS, MTA.

# netstat -m gives:
627 mbufs in use:
561 mbufs allocated to data
4 mbufs allocated to packet headers
62 mbufs allocated to socket names and addresses
560/974/6144 mbuf clusters in use (current/peak/max)
2276 Kbytes allocated to network (56% in use)
0 requests for memory denied
0 requests for memory delayed
0 calls to protocol drain routines

Interupts are something about 5-9%.

# top
load averages: 0.22, 0.24, 0.24 17:40:04
63 processes: 62 idle, 1 on processor
CPU states: 21.2% user, 0.0% nice, 5.5% system, 7.8% interrupt, 65.5% idle
Memory: Real: 137M/250M act/tot Free: 247M Swap: 0K/1026M used/tot

I also try to increase net.inet.udp.sendspace and recvspace.

What can be causing this message?

Thanks for help
