Hi Folks,

I've got a 3.9 Tb zpool, and it is casing kernel panics on my Solaris  
10 280r (SPARC) server.

The message I get on panic is this:

panic[cpu1]/thread=2a100a95cc0: zfs: freeing free segment  
(offset=423713792 size=1024)

This seems to come about when the zpool is being used or being  
scrubbed - about twice a day at the moment. After the reboot, the  
scrub seems to have been forgotten about - I can't get a zpool scrub  
to complete.

Any suggestions very much appreciated...
