I should also point out that I get those same Signal 6's with `make' compiled without KQUEUE, so the problem is not with KQUEUE itself. So while I do think there is *some* subtle bug that is still lurking around, I suspect that the issue about KQUEUE and `make' can probably be crossed off the to-do list. That's my experience, at least. YMMV, etc. >... I just now realized that I ended up with 1.76... I guess >I should try it one more time with 1.75 instead of 1.76.

Or maybe it's a red herring. Another variable that is perhaps worth noting is that I am still running SCHED_4BSD. This is on a snapshot of 6.x-current from sometime last Thursday afternoon, except for changing the version of src/sys/kern/kern_lock.c . -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
