named[93]: general: error: 48/Address already in use

[Dan Mason]

One of my resolvers is receiving this error between 4 and 8 times a
day.

There is no pattern or interval to this error.  This machine is running
FreeBSD 4.11-RELEASE, and bind 9.3.2.  I'm not positive what the
original compile-time options were.  This bind process has been running
since Feburary 8 2005, and only has about 200M of cache.

This error isn't causing a noticable symptom, other than the syslog
entries.  I was curious though, if anyone had seen this error before.
Thanks!
