--UugvWAfsgieZRqgk Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Hi, Matthew, Would you please have INVARIANTS and INVARIANT_SUPPORT in your kernel configuration and try again? I think it would be helpful for us to figure out what was happening. In addition, Matt Dillon has suggested[1] that you run his vmpageinfo program on the dump, please have a try. [1] http://lists.freebsd.org/pipermail/freebsd-hackers/2004-November/008954= .html Thanks in advance!
