Hi all.
I've just encountered a SunFire V240 which panics whenever a zpool
scrub is done, or whenever two of the filesystems are accessed.
After some rummaging around I came across bug report 6537415 from
July this year, which seems to be an exact replica of the panic msgbuf I see.
I'm wondering if there was a patch or something released for this, or was
it put down to cosmic radiation? We have a good many systems here on
Solaris 10 6/06 and ZFS, all of which are running nicely except this one, which
seems to
have gotten itself into a right old state.
Thanks for any tips.
