Hi all I have been struggling with this CLOSE_WAITS.

I have an Request Tracker installed on CEntOS 6.7 (64 bit) RT rt-4.2.12 and Apache httpd-2.2.31. I can log in and all, but after a while I am seeing CLOSE_WAIT socket are created for each selection that I make on the dashboard. Eventually the system goes unresponsive.

root@iplrt logs]# netstat -nalp | grep -i wait
tcp 1 0 192.168.11.254:80 192.168.11.118:57076 CLOSE_WAIT 3176/httpd
tcp 1 0 192.168.11.254:80 192.168.11.118:57083 CLOSE_WAIT 3177/httpd
tcp 1 0 192.168.11.254:80 192.168.11.118:57082 CLOSE_WAIT 3185/httpd
tcp 1 0 192.168.11.254:80 192.168.11.118:57084 CLOSE_WAIT 3365/httpd
[root@iplrt logs]#

I don't see any errors in the logs! I have downgraded both RT and Apache with no luck and I am STUCK no ware to goooooo

Can some one tell me how to go about diagnosing this

Thanks and Regards

tcpdump on the respective network interface, both on the client and the server side.
