This seems much too repeatable to be hardware. The more times I repeat my testing, the more consistent the problem seems. (but I'll spare you the details until I narrow it down even more...). I am sure I have rebuilt make several times, because I am switching between "make WITH_KQUEUE" and make without kqueue, and I do complete recompiles each time I switch. These signal-6's are not coming up in "normal operation" for me. It is only when I have been stress-testing changes to the make command. >Are you using gvinum? No. I am not that adventurous when it comes to filesystems. I use plain UFS2. I even turn off background FSCK-ing because I'm not sure I trust it yet... Please note that I did not mean to make a big deal about these signal 6's. I have to go out-of-my-way to trigger the problem, but now that I know what to do I can trigger it at will. Given that I can repeat it I do intend to keep poking away at it, but I do not consider this a serious issue. So unless a lot of other people start reporting something similar, I do not expect anyone else to spend any of their own time trying to pin it down. It's the kind of annoying little anomaly that will drive me nuts unless I pin it down, but in the greater scheme of things it is probably irrelevant. I do appreciate the suggestions because they give me more ideas of things I want to try when I have the time. But I don't expect anyone to worry about this. Certainly I am not worried about it. The main thing I wished to say was just "Great progress has been made wrt using KQUEUE for make", given how well it has stood up to my repeated hammering of it. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
