I've followed the steps at http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html for getting a crash dump but I'm not getting dumps. Here's the relevant line from rc.conf: dumpdev="/dev/da1s1b" And it seems to be OK as dumpon has no problem when I set this manually: blacksheep# dumpon -v /dev/da1s1b kernel dumps on /dev/da1s1b My swap partition is 750 MB and the total system memory is 384 MB. Any ideas on what I might be doing wrong? Thanks, Drew -- Visit The Alchemist's Warehouse Magic Tricks, DVDs, Videos, Books, & More! http://www.alchemistswarehouse.com
