The stack trace in your panic looks a lot like that found in
6935256 Corrupted DNLC caused panic in dnlc_purge_vfsp()
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6935256
It''s marked as a dup of another bug that was fixed before Solaris 11
Express. In a few seconds of looking at 6935256 and 6923355, I don''t
understand how they are related. Assuming you have a support
contract, I would advise opening a support case to get someone to look
into it.
