This is likely the issue described in this message: http://lists.freebsd.org/pipermail/freebsd-fs/2008-October/005217.html The nfs fix has been committed to head and stable/7 (7.1-RELEASE has the fix). The fix prevents system from panicing but you still can't access the snapshot directory with readdirplus enabled nfs clients. As a workaround you can disable readdirplus support if your nfs client allows it. -- Jaakko
