Thanks for that reminder. I forget how practical that is at times. I agree with throwing ram and trimming swap space down. On windows they want a huge swap so the system can dump. I think the last time I cared to spend the time to trouble shoot a windows machine via a dump was over 12 years ago. Maybe more. Is a lot cheaper and quicker to just start rebuilding most of the time. Christopher G.
