Hi All, I'm seeing strange behavior. After some time of work I'm getting to many CLOSE_WAIT connections from clients, and the number is increasing.
# netstat -tonp | grep CLOSE tcp 1 0 111.22.33.44:80 10.214.35.4:52429 CLOSE_WAIT 14531/traffic_serve off (0.00/0/0) tcp 1 0 111.22.33.44:80 11.202.242.217:51424 CLOSE_WAIT 14531/traffic_serve off (0.00/0/0) tcp 1 0 111.22.33.44:80 12.153.247.234:49950 CLOSE_WAIT 14531/traffic_serve off (0.00/0/0) tcp 1 0 111.22.33.44:80 13.179.104.225:58900 CLOSE_WAIT 14531/traffic_serve off (0.00/0/0) To the end of the day, the amount of CLOSE_WAIT connections will be more then 100. Due to this issue, I'm getting incorrect number of proxy.node.current_client_connections (as example, I can see hundred of proxy.node.current_client_connections, while there is almost no traffic on the server). My timeouts: CONFIG proxy.config.http.keep_alive_no_activity_timeout_in INT 30 CONFIG proxy.config.http.keep_alive_no_activity_timeout_out INT 120 CONFIG proxy.config.http.transaction_no_activity_timeout_in INT 30 CONFIG proxy.config.http.transaction_no_activity_timeout_out INT 30 CONFIG proxy.config.http.transaction_active_timeout_in INT 0 CONFIG proxy.config.http.transaction_active_timeout_out INT 0 CONFIG proxy.config.http.accept_no_activity_timeout INT 120 CONFIG proxy.config.http.background_fill_active_timeout INT 60 CONFIG proxy.config.http.background_fill_completed_threshold FLOAT 0.500000 OS: CenOS 6.3 2.6.32-279.14.1.el6.x86_64 traffic_server - 3.3.1-dev - (build # 11318) Changing of net.ipv4.tcp_tw_reuse had no any effect. Any suggestions will be very appreciated. Thanks,
