It still runs networking daemons into a frozen zoneli state on heavy/(D)DOS network loads. Such processes cant be kill-9ed so there is no way to recover from it. (think frozen sshd and a very remote/headless server). See the stress test panic called 'Ran out of "128 Bucket" ' on the 6.2 todo list and my own latest test here: http://www.maniacs.se/~junics/temp/vmstat-z.txt This test was on a new 6.2-RC2 install with no zone limit tweaks nor any sbsize limits in /etc/login.conf. I just made a vm disk image with replication instructions, however Peter Holm have replicated it with his own tools so i have not bothered with it until now. > Unless further testing turns up something new > RC2, which is available now for dowloading, will be the last of the > Release Candidates and 6.2-RELEASE should be ready in about 2 weeks. > Your continued help with testing would be greatly appreciated.
