While not a guru, I think I can tell you the issue.  It looks like
the snapshot was full (says 100.00).  The snapshot is unusable at
that point.  Maybe it wasn't before you started the merge, and the
merge sets it to 100.00 when it starts, I haven't noticed.

What was the snapshot percent used before you started the merge?
