The instability is only transitory. I am working the issues (along with the threads stuff) right now. There have been continuing wierd problems with swap space utilization, and the changes should fix it. Do you have a copy of your tests that you could send to me? The more tools I have to fix the problems, the quicker they'll get solved. -- John | Never try to teach a pig to sing, dyson@freebsd.org | it just makes you look stupid, jdyson@nc.com | and it irritates the pig.
