I understand how such things can happen and that no slight was intended. If FreeBSD was broken in some way then we certainly would include that in the Apache documentation in the appropriate place, after being sure that whoever is responsible is aware of it. I do think I prefer the other error in the release notes that you fixed, which was: An in-kernel linker is implemented and intended to replace the lkm system with the bogosity that goes with it <g> > > Earlier on, it was a real problem because httpd was depending on alarm() to > wake up a sleep and depending on the SIGALRM handler not being called.

Mmm. I am having some trouble figuring out where this would be since Apache, as a general rule with a couple of exceptions, normally doesn't call sleep(). 1.2 did use sleep() in the parent process but I don't see where any SIGALRMs would be involved there. bccing to the Apache development list (since it doesn't accept posts from non-subscribers).
