Several questions, and a problem: - How can I tell if the 1.0 *A* upgrade has been applied to my system? - I'm looking for recommendations on NeXT system administration/tuning. Can someone point me in the right direction? - I'm just guessing, but I thought the SHAR utility was common to all unix systems. Mach (at least what's running on my NeXT machine) doesn't seem to have it. Why? I'm sure I can find sources in the meantime, but I was surprised it wasn't there. Finally, a machine-crashing (sort of) problem. Need help. I was compiling some code yesterday. At some point during the MAKE process, the machine entered some form of thrashing state. I could get response, sort of, as long as I didn't do any real demanding things (like "fg" my emacs session). Still, I ultimately had to power down the machine after doing a command-`, since it was all tied up in some form of knots. I'm guessing this happened because I have an 8mb system. I haven't diddled any system parms. The swap file in /private/vm/swapfile is 16megs. Yet the /etc/swaptab entry has a low water mark of 20 megs. So some questions: - Am I thrashing for lack of swapfile? - How can I tell how much swapfile is in use, or do any kind of reasonable paging/load monitoring. VM_STAT just doesn't seem to tell me much. - How do I grow the mach swapfile? Unix wizards I know plead ignorance about Mach, and I don't know any Unix tuning trivia (yet). HELP! This was my first attempt at compiling any reasonable applications. I can't have my machine locking up every time I try to do real work. I'm sure many NeXT'ers will find answers to these questions useful. Dave
