Hello,

when checking systat -ip I see the value for "socket buffer full" with
values different from 0, I see 1, 2, up to 55 in one occasion.

I asked on IRC and it was mentioned I should try to up
kern.ipc.soacceptqueue to 1024 from the default 128, but I could still see
values over 0 in "socket buffer full".

How can I tune this buffer?

We have a lot of UDP traffic (the server is a PBX serving around 200 agents
with avg 50 concurrent calls.

thank you
Best
Ray
