I have a working prototype as of last night. There should be something committable in the next week or two. When I boot my 2GB machine and force a crash dump from single user mode, the fully debuggable vmcore file is in the 40-50MB range. A busy machine with 12GB ram took about 150MB to dump. There are still some things to work out. It was written for the amd64 kernel, but can be ported to i386. -Peter _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
