Since you only have one single kernel image the thread the zone created
is stuck doing a read()/write()  in biowait() waiting for the I/O to
Sometime in the future the underlying device handling that I/O should
and trigger an interrupt calling biodone().
I would look in /var/adm/messages and have a crashdump of the kernel if it
was collected.
Keep in mind there is one single kernel image.

Subject: Re: [zones-discuss] Preventing a Local zone hang from having to
reboot the global zone

This will re-boot the zone from the global zone, 
    zoneadm -z hostnamezoneX boot

Hello All,

I had a case where a hung process in a local zone (ie blocked on 

biowait), caused the local zone to become unresponsive. Couldn't shut 

the zone down, kill the process, etc.  The only way to have zone become 

responsive was to reboot the global zone.  Is there any thing that can 

be done to prevent this. ie (not having to reboot the global zone and 

only reboot the local zone)
