Yes, I did that already (installed the latest binary), though it seems significantly out of date.

The problem is that apache crashes. The event viewer says

This happens intermittently during load testing, and I think I've traced to what type of load testing does it. Using pylot or ab, it doesn't crash. But, if I do the following procedure, I can get it to crash:

1. Save a bunch of tabs in a browser, in my case I'm using Safari for Windows 3.1.1 (525.17).
2. Click on the bookmark of the tabs over and over, before they get done rendering.
3. I think safari is canceling the client requests or somehow dropping them mid-way through. I presume this is a factor.
