My machine is working with the kernel that comes with 6.1-STABLE (I archived this good kernel before upgrade the OS to 6.2).
No, I'm not using geom.

Can you send your dmesg.boot and "sysctl -a  kern" output?

I'm just curious here, but are you by any chance using geom at all? The only machine I have that seems to be affected like this (where netstat -m doesn't seem to indicate a problem with mbufs) is using gmirror ... the rest all use hardware RAID controllers ...

  Its a long shot, but so far, its the only one I seem to be able to draw :(

I've had a problem with one of my FreeBSD servers, the machine has stopped
its network services and then sent these messages:

-Mar 27 13:00:03 anubis dhcpd: send_packet: No buffer space available
-Mar 27 13:00:26 anubis routed[431]: Send bcast sendto(em0, No buffer space available

The messages were repeated a lot of times before a temporary solution. I've
changed the kernel(FreeBSD 6.2) to an older one(FreeBSD 6.1) and since then
it's been working well. What happened?

P.S.: I can give more informations if necessary.
