Hello! I have a litle problem with my unbound:
unbound: notice: sendto failed: No buffer space available
I think, I should increase net.inet.udp.sendspace, but I don't really
understand what size do i need.
Is there any information about calculating needed buffer space?
It is probably not net.inet.udp.sendspace since that value only affects
how big a packet you can send per UDP. The send buffer is only used to
move the packet to the kernel and is empty after every send.
Please check a) if there are any failures to allocate mbufs (netstat -m
and vmstat -m) and b) interface errors (netstat -i)
I don't really know what all this numbers mean,
netstat -m:
749 mbufs in use:
571 mbufs allocated to data
97 mbufs allocated to packet headers
81 mbufs allocated to socket names and addresses
20/2232 mbuf 2048 byte clusters in use (current/peak)

vmstat -m it pretty long. The one string that has "fail" counter is pfstate:
pfstate 328 78561518 90858 11156 92096 90849 1247 4167 0
8 0
and here is netstat:
em1 1500 <Link> 68:05:ca:22:d8:d3 1671803452 128 2136354673
21 0
em1 1500 172.16/12 gater 1671803452 128 2136354673 21 0
i have unbound binded to em1
Does this mean something?
