If running the tests for a long time does not cause a panic, that is often interpreted as "success". A different view is that the test suite is broken :) Look at the (regression) tests in stress2/misc, and run them by ./all.sh -o This should take some 36 hours on modern hardware. Remember to add a swap disk, as many of the tests rely on VM pressure. > Thanks, > Susan Stanziano > _______________________________________________ > freebsd-testing@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-testing > To unsubscribe, send any mail to "freebsd-testing-unsubscribe@freebsd.org" -- Peter
