This looks consistent with the problem we are working on right now.
When the file system gets close to being filled it runs around finding all the
small left over extents. At some point one of the writes goes to far and
scribbles
over
the the ag structures. We are getting close to resolving the bug... give us a
day
or
so.
The core dump on the repair is not a good thing although... do you have a stack
trace?
