Yes, older NetBSDs. What do you think OpenBSD is? Nah, just kidding. I don't remember what tests I did at the time. I do remember that I couldn't reproduce it as easily as I wanted to, and the likely cause was that I was doing my tests on a kernel more recent than the 2.0 of my prod servers. > But yes, with some NetBSD versions it does leak one pipe per each > died process because kqueue doesn't notice that the pipe was closed > by the other side and give an event, or something like that. Which does look like what is experienced here. Now, I don't know if we can locate easily what fix needs to be applied to OpenBSD. -- Quentin Garnier - [EMAIL PROTECTED] - [EMAIL PROTECTED] "You could have made it, spitting out benchmarks Owe it to yourself not to fail" Amplifico, Spitting Out Benchmarks, Hometakes Vol. 2, 2005.
