Hi again, I did some further tests with Apache under FreeBSD 6.0 - Jail, and unfortunately, there is still the same annoying problem: suddenly the log starts being filled with hundreds of lines "Connection refused: connect to listener on 0.0.0.0:80", and Apache does not respond anymore. I have a log example, that shows the Apache freeze: -------------------------- [Sat Jul 15 14:25:36 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/adserver [Sat Jul 15 14:25:37 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/phpAdsNew [Sat Jul 15 14:25:37 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/phpadsnew [Sat Jul 15 14:25:37 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/phpads [Sat Jul 15 14:25:37 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/Ads [Sat Jul 15 14:25:38 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/ads [Sat Jul 15 14:25:38 2006] [error] [client 66.147.238.238] script '/home/verticaldrape/www/data/xmlrpc.php' not found or unabl e to stat [Sat Jul 15 14:25:39 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/xmlrpc [Sat Jul 15 14:25:39 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/xmlsrv [Sat Jul 15 14:25:39 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/blog [Sat Jul 15 14:25:39 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/drupal [Sat Jul 15 14:25:40 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/community [Sat Jul 15 14:25:40 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/blogs [Sat Jul 15 14:25:40 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/blogs [Sat Jul 15 14:25:40 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/blog [Sat Jul 15 14:25:41 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/blogtest [Sat Jul 15 14:25:41 2006] [error] [client 66.147.238.238] File does not exist: /home/verticaldrape/www/data/b2 [Sat Jul 15 14:25:42 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sat Jul 15 14:25:43 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sat Jul 15 14:25:44 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sat Jul 15 14:25:45 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sat Jul 15 14:25:46 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sat Jul 15 14:25:47 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sat Jul 15 14:25:48 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sat Jul 15 14:25:49 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sat Jul 15 14:25:50 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sat Jul 15 14:25:51 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [snip] [Sun Jul 16 04:50:10 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sun Jul 16 04:50:11 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sun Jul 16 04:50:12 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sun Jul 16 04:50:13 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sun Jul 16 04:50:14 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sun Jul 16 04:50:15 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sun Jul 16 04:50:16 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sun Jul 16 04:50:17 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sun Jul 16 04:50:18 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sun Jul 16 04:50:19 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sun Jul 16 04:50:20 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 [Sun Jul 16 04:50:21 2006] [warn] (61)Connection refused: connect to listener on 0.0.0.0:80 -------------------------- The freeze appears apparently under high load, with about 4 connections a second from a robot. I made 2 changes in httpd.conf the last days, which apparently did not help: 1. Commented out: #LoadModule ssl_module libexec/apache22/mod_ssl.so 2. Added: AcceptFilter http none Does anyone have an idea where this problem might come from? I'm pretty sure it must be linked to the jail system in some way... Any chance things might be corrected in FreeBSD 6.1? My jails are all configured like this: jail_j29_hostname="j29.attiksystem.ch" jail_j29_ip="83.222.129.29" jail_j29_rootdir="/usr/jails/j29" jail_j29_exec="/bin/sh /etc/rc" jail_j29_devfs_enable="YES" I'm using the network interface "em" driver.
