I have several installations of apache running on a FreeBSD 4.9 system (soon to be replaced with a 5.3 system). One particular one, a 1.3.27 plus Ben-SSL, with PHP, has a LOT of its processes in "sbwait" state. I have been googling and did not find much that explained what this was symptomatic of. One from Terry Lambert had some interesting info, but this system is not that highly loaded and based on the clientele of the site, I would expect that they are all on high speed links (a video gaming site -- mlgpro.com), and he had mentioned that this might be from slow clients. Could this be a symptom of a denial of service attack? What does it mean (in detail) and are there things I can adjust to make it not happen? Thanks Chad
