Hi !
I really enjoy the list and I learn a lot from it, but right now I find an intresting problem and I can't
find the solution for it .
When my server (Raq4) make a connection with a client IP , it opens more than two ports to comunicate with it !
ex:
tcp 0 0 ns1.myhost.net:www 193.231.188.111.ca:2209 ESTABLISHED
tcp 0 0 ns1.myhost.net:www 193.231.188.111.ca:2208 ESTABLISHED
tcp 0 0 ns1.myhost.net:www proxy.ac.tuiasi.r:41379 TIME_WAIT
tcp 0 3185 ns1.myhost.net:www proxy.ac.tuiasi.r:41378 FIN_WAIT1
tcp 0 0 ns1.myhost.net:www proxy.ac.tuiasi.r:41377 TIME_WAIT
tcp 0 0 ns1.myhost.net:www proxy.ac.tuiasi.r:41376 TIME_WAIT
tcp 0 3360 ns1.myhost.net:www proxy.ac.tuiasi.r:41219 FIN_WAIT1
the worst part is, that sometimes the server forget to close all connections and refuse to connect with others !
ex:
netstat -a

when I run the top comand , I see in the list :
kswapd <defunct>
mysqld <defunct>
In this case I have only one choice : reboot the server from ssh !
I have this settings in my httpd.conf :
Timeout 300
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 15
MinSpareServers 5
MaxSpareServers 10
StartServers 5
MaxClients 120
MaxRequestsPerChild 500
Please help me a.s.a.p. !
Thanks
Paul
