Bug ID: 65689 Summary: proxy connections to target left in CLOSE_WAIT state Product: Apache httpd-2 Version: 2.4.51 Hardware: PC Status: NEW Severity: normal Priority: P2 Component: mod_proxy Assignee: bugs@httpd.apache.org Reporter: lothar.web...@gmail.com Target Milestone: --- Hi all, since we updated apache from 2.4.46 to 2.4.51 we have a lot of open connections to destination hanging in "CLOSE_WAIT" state. The connection is closed by target after a 10 secs. with a TCP RST. Which causes alerts in our monitoring system. I tried to disable keepalive with SetEnv proxy-nokeepalive 1 We are using this config: <IfModule mod_proxy.c> ProxyRequests On AllowCONNECT 443 SetEnv proxy-nokeepalive 1 <Proxy "*"> Require all granted </Proxy> </IfModule> The Client is initiation a connection via method CONNECT: CONNECT www.example.com:443 HTTP/1.1 Somehow disable keepalive is not working. Also the behavior has changed, with apache 2.4.46 the connection was closed smoothly: apache -> target ACK target -> apache FIN,ACK apache -> target ACK apache -> target FIN,ACK With apache 2.4.51 the last FIN,ACK is not sent anymore but we receive target -> apache RST, ACK after 10 sec. Could this be fixed, or is there any workaround ( like disable keepalive) Thanks a lot!
