Hi! Last Thursday one of the sites I host got slashdotted (http://www.slashdot.com/) and amazingly FreeBSD 4.3 on PIII 600 Mhz with 128 MB RAM took the load gracefully. I.e. until around 5 PM EST when I got messages like: /kernel: xl0: no memory for rx list -- packet dropped! at the console... So what I did is, I terminated some of the daemon's that were not really used as a couple of httpd server, etc. This seemed to solve the problem, however... When I run a netstat -na right now I get the impression that there is still some garbadge in memory from this experience: As: tcp4 0 15360 63.105.9.61.20 217.80.179.220.2822 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.219.43.81.2591 LAST_ACK tcp4 0 15360 63.105.9.61.20 200.11.220.5.2535 LAST_ACK tcp4 0 15360 63.105.9.61.20 200.11.220.5.1736 LAST_ACK tcp4 0 15360 63.105.9.61.20 200.11.220.5.1735 LAST_ACK tcp4 0 15360 63.105.9.61.20 202.133.131.44.3651 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.4486 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.4338 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.3452 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.3449 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.1825 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.2922 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.2390 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.2310 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.1598 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.1597 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.1556 LAST_ACK tcp4 0 15360 63.105.9.61.20 193.124.148.213.1553 LAST_ACK tcp4 0 15360 63.105.9.61.20 203.195.181.4.1440 LAST_ACK I am sure this has been in there the last at least 24 hours and I can see nothing is happening. I suspect that this is because of the no memory for rx list, but I am not quite sure. I was kinda a cool feeling though that FreeBSD didn't give up, but still runs!!! Is there anyway to clean this up without having to reboot the system? Thanks! Jan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
