It seems to happen perhaps 20-25 percent of the time and after it 
happens the zone is "infected" until system reboot.

If it matters, I am using lightly-loaded 8-core, 16-thread Xeon-D 
hardware.

Interestingly, I just noticed that my most recent effort (cribbed from 
OmniOS system upgrade admin notes) did this:

   for zone in base pkgbuild ftp www src smtp
   do
     zlogin $zone shutdown -i5 -g0 -y
   done

rather than this

   for zone in base pkgbuild ftp www src smtp
   do
     zoneadm -z $zone shutdown
   done

Normally I would use 'zoneadm' to do the shutdown.  However, I am 
pretty sure that the former (based on 'zlogin') encountered the same 
problem.  If so, that is very interesting.

In the shutdown loop, two of the zones encountered the problem.
