From my own experience with tuning OSs (specifically >Solaris 2.x), I'd agree with David's assessment.

I'm also a bit incredulous since wcarchive does far more TCP/IP than most other machines in the world, has months of uptime and no detectable buffer leaks. I want to be clear about this: If there was a bug that I could identify, I'd fix it immediately.
