Or was this particular problem introduced more recently than the 6.2 branch? I have two apparently similarly configured systems running 6.2p8, with identical hardware, identical apps, and identical load, and I have at least attempted to configure them the same way. Both have /var/crash set up and "dumpon" enabled in rc.conf. Both crashed in the last week. I got a dump on one, which I now need to analyze, but have twice failed to get a dump on the other. (Once this past week, once the previous month.) -- Clifton -- Clifton Royston -- cliftonr@iandicomputing.com / cliftonr@lava.net President - I and I Computing * http://www.iandicomputing.com/ Custom programming, network design, systems and network consulting services _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd.org"
