so it turns out that it is a bug. You can run into this issue when upgrading from any revision prior to svn_127.
See http://defect.opensolaris.org/bz/show_bug.cgi?id=12380 for the details. The http://defect.opensolaris.org/bz/show_bug.cgi?id=13437 entry is probably also worth looking at if you're upgrading from svn_111 although this is not as major an issue as the above. -- This message posted from opensolaris.org
