Hi, I hope this list can help me. Our company bought a brand new P-III 933Mhz 1GB server few months ago for our Web and Mail services. We run FreeBSD 4.2-STABLE (Jan 17 2001). The Web server is Apache 1.3.19 with PHP 4.0.4pl1. Recently, and after hosting a heavily accessed Web site on it, the server is showing signs of "tiredness" by not accepting new connections to the Web server. At this time, I can see that the CPU usage (idle) is more than 90%, and that's why I am almost convinced that it's a lack of connection resources in the FreeBSD system that is causing the problem. Apache is configured to run a maximum of 15 clients concurrently, and each of them can handle up to 200 connections. That's a 3000 connections limit. I wanted to ask you whether it's possible to see how many active connections (keep-alive included) are being used by the OS and is there a way to know what's the maximum limit allowed in the system? I suspect it's a system control variable, but I couldn't find it after checking the list of I got from 'sysctl -a' Thank you for your help, Noor To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
