[root@fosco dphoenix]# netstat -a|grep http|grep ESTABLISHED|wc -l
141
[root@fosco dphoenix]# ps aux|grep httpd|wc -l
186
[root@fosco dphoenix]# netstat -a|grep http|grep TIME_WAIT|wc -l
217
[root@fosco dphoenix]# netstat -a|grep http|wc -l
537
and the load balancer report 1001 connections...netstat -a|grep http
does not even add up to this.
fosco Alive 1001 1 42 1102
So what i can conclude from what you said is that
there are more connections waiting to close for some strange reason
than establishing connection....btw what is FIN_1 in netstat?
Anyways something is wrong here...1001 connections the load balancer is
reporting.....those 1102 state transitions were from earlier today
when i got rid of thttpd which was causing connection resets...moved
back to ports collection of apache13 static server.
Anyone with ideas or anyone that has an arrowpoint LB?
