</span>No. And as mentioned before this is a Solaris 11 system, so /etc/system is<br>
(mostly) irrelevant, as the IP settings are all done with ipadm now.<br>

</span>That, as well as the script and examples you provided, won't help me a lot,<br>
as I am looking at UDP receive buffer overflows, not TCP.<br>
<br>
I have set udp_max_buf to 4MB now and udp_send_buf & udp_recv_buf to 2MB<br>
each, then restarted BIND.<br>
It seems to be working better now as I don't see that much receive buffer<br>
overflows anymore.<br>
<br>
However, the initial question still stands. How can I reconfigure BIND to<br>
pick up the data faster from the receive buffer ?<br>

<br>
</span>Yes, of course.<br>
