B-) It seems I may have found yet another bug in the NeXT operating system that causes the machine to crash inadvertently. I was downloading some sounds earlier today, and while doing that I played one of the sounds (which was still downloading) to find out what it was. The machine proceeded to produce a system panic. ("MMU: invalid descriptor during table walk", or something like that.) I was able to reproduce this at least twice more. (Yes, I crashed this machine again and another one.) Any ideas?

I've been able to crash the machine now and again when doing various things with the sounddriver. To me most of the crashing I can do is related to using the sounddriver, but then again, that is what I do most of the day so you might expect I would find some bugs in it. ----------------------------------------------------- Replies can have NeXT attachments in them >From: smithw@mathnx.byu.edu (William V.

I guess you would need to implement a file locking mechanism to prevent things like you mentioned.
