I started getting this:

from this (which I snarfed from someones post, and which is run from
/etc/rc.local):

if [ -f /var/log/dmesglog ]; then
   echo -n 'checking system bootlog:'
   mv -f /var/log/dmesglog.3 /var/log/dmesglog.4
   mv -f /var/log/dmesglog.2 /var/log/dmesglog.3
   mv -f /var/log/dmesglog.1 /var/log/dmesglog.2
   mv -f /var/log/dmesglog.0 /var/log/dmesglog.1
   mv -f /var/log/dmesglog /var/log/dmesglog.0
   dmesg | tail -r | sed /^NetBSD/q | tail -r > /var/log/dmesglog
   rm -f /tmp/diff.$$
   diff -bc /var/log/dmesglog.0 /var/log/dmesglog > /tmp/diff.$$
   if [ -s /tmp/diff.$$ ]; then
      cat /tmp/diff.$$ | mail -s "system bootlog changed" root
      echo ' changed.'
   else
      echo ' no change.'
   fi
   rm -f /tmp/diff.$$
fi

I remember seeing some words of a change with fd's on source-changes
right before this started happening. sendmail works normally after the
system is fully up, though.

The box is a NetBSD/i386 1.4_ALPHA, ideas?
