The problem is known, but I haven't seen any word from developers on the lists as to whether or not a fix is underway. PR: http://www.freebsd.org/cgi/query-pr.cgi?pr=148655 Post: http://lists.freebsd.org/pipermail/freebsd-fs/2010-July/009008.html I expect more users to start reporting this issue, as it's quite major/serious. It should probably be added to the 8.1-RELEASE Errata given its severity. -- | Jeremy Chadwick jdc@parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
