 Hello,

 I am unable to use DNSPort on OpenBSD. The syslog says the port has opened
 correctly, and I see it in netstat:
 {{{
 udp          0      0  localhost.10000        *.*
 }}}

 However, there is no "LISTEN" as you can see. And when I use nslookup, I
 get:
 {{{
 Abort trap (core dumped)
 }}}

 Also when I run a second instance with only DNSPort set to the same, this
 is the output:
