To anyone who has been following my little trials with thttpd 2.17 and FreeBSD 4.x stable, I have one more piece of news. After remaking world, and recompiling our customized thttpd from scratch, we are still not working. In fact, I think it is worse. A ktrace and a truss both indicate that thttpd not surving very long, 10 seconds or less, then the process completely dies. The perl wrapper around thttpd had just been restarting it, so we didn't really notice at first. Obviously that is the source of our dropped connections when the load gets high enough. Since other people are uning thttpd on the 4.x branch, I doubt thttpd itself is to blaime. Perhaps some of the patches to thttpd we added arn't playing well with 4.x, or perhaps somthing has gone wrong on a hardware level on that machine. I might back ot to 3.5-S and see if it exhibits the same behavior. Either way, more testing/checking is called for on my part. I do thank the list for the input they have given me. I certainly don't want to appear as ungrateful. -Marius M.
