I just looked at our lab machines running NetBSD/i386 2.99.10 and 4 of them
have named.core's created in the last week (any before that would have been
cleaned out). All the cores correspond to a shutdown (but not every
shutdown) and all the core's give the following backtrace:
#0 0x481fe373 in kill () from /usr/lib/libc.so.12
#1 0x481dbab4 in pthread__assertfunc () from /usr/lib/libpthread.so.0
#2 0x481d78eb in pthread__next () from /usr/lib/libpthread.so.0
#3 0x481d595b in pthread__upcall () from /usr/lib/libpthread.so.0
These are basically caching only named's doing no dynamic DNS or anything
