Failover scenario is not performed with httpd balancer - balancer fails to respond ---------------------------------------------------------------------------------- Key: MODCLUSTER-675 URL: https://issues.redhat.com/browse/MODCLUSTER-675 Project: mod_cluster Issue Type: Bug Components: Native (httpd modules) Affects Versions: 1.3.8.Final Environment: RHEL 7, CentOS 7 on x86_64 platform Reporter: Jan Kasik Assignee: Jean-Frederic Clere Priority: Blocker Fix For: 1.3.12.Final Attachments: error_log, httpd.zip, wildfly-16.0.0.Beta1-SNAPSHOT.zip When second request in failover scenario is made to check whether the failover was done, server fails to respond. With Undertow as a balancer, this behavior cannot be reproduced. When I replace the jvmroute part by worker which is still alive, I got expected response. {noformat}# curl -v --cookie "JSESSIONID=54yxdncGr5im0fBLqIIUMon0klbS66X16aYC_cVW.jboss-eap-7.2-3" http://172.17.0.2:2080/clusterbench/jvmroute * About to connect() to 172.17.0.2 port 2080 (#0) * Trying 172.17.0.2... * Connected to 172.17.0.2 (172.17.0.2) port 2080 (#0) > GET /clusterbench/jvmroute HTTP/1.1 > User-Agent: curl/7.29.0 > Host: 172.17.0.2:2080 > Accept: */* > Cookie: JSESSIONID=54yxdncGr5im0fBLqIIUMon0klbS66X16aYC_cVW.jboss-eap-7.2-3 > * Empty reply from server * Connection #0 to host 172.17.0.2 left intact curl: (52) Empty reply from server {noformat}
