Is it? I searched and searched and never found any hits or PR's regarding this.

Not sure where you looked then, but I not only saw the discussion multiple times on various lists, I know I posted about our experiences with it. :)

When was it first fixed? 5.x? 6.x? or not until 7?

The reason I suggested moving to 7 is that it was branched most recently, has the best new features, etc. If you have to jump FreeBSD versions, this is the one that will get you the most bang for your buck. If you aren't using SMP boxes and have a risk-averse environment, the latest version of 6 will get you where you need to go.

Please also note that while this problem has been tweaked somewhat in later versions, it's not always a problem that can be "fixed" in the OS. I'm guessing that you're using an Apache web server, since this is the application that most often leads to this problem. There used to be some helpful hints on Apache's web site for ways you can tune it to reduce the problem, not sure if they're still there or not.
