9.3.0 coring on FreeBSD 5.3-STABLE

[Alex R]

Before I had a problem with named coring on sighup. My solution to that
problem was to use rndc reload. Now named keeps on coring sporadically when
I'm not doing anything besides using it for normal lookups. Where can I look
to start debugging this problem? Does named leave a core file anywhere? Also
I'm not sure if this has anything to do with it but it is a secondary DNS
for the .lan zone I use internally on my home LAN.
