Not really, it's consistent with PowerDNS only accept()ing a single
connection.
The next step probably is looking at "strace -f -p SERVER-PID" output
(or what your local truss/strace equivalent is called), although the
interesting messages will probably be lost in the noise caused by
processing UDP queries.
