[JBoss JIRA] (MODCLUSTER-416) mod_cluster Connected count shows improper inflation

[JBoss JIRA] (MODCLUSTER-427) mod_cluster can break stickiness for the first request on new child processes

by Michal Babacek (JIRA)

[ https://issues.jboss.org/browse/MODCLUSTER-427?page=com.atlassian.jira.pl... ] Michal Babacek updated MODCLUSTER-427: -------------------------------------- Bugzilla Update: (was: Perform) > mod_cluster can break stickiness for the first request on new child processes > ----------------------------------------------------------------------------- > > Key: MODCLUSTER-427 > URL: https://issues.jboss.org/browse/MODCLUSTER-427 > Project: mod_cluster > Issue Type: Bug > Components: Native (httpd modules) > Affects Versions: 1.2.9.Final, 1.3.1.Alpha1 > Environment: JBoss EAP 6.3.0 > Reporter: Aaron Ogburn > Assignee: Aaron Ogburn > Fix For: 1.2.10.Final, 1.3.1.Alpha3 > > > mod_cluster can break stickiness for the first request on new child processes. It looks like this occurs specifically when "CreateBalancers 1" is used. Prefork typically makes this much worse as well. > My debugging showed that the proxy_balancer would exist, but it would essentially be empty in the new child process. find_session_route/find_route_worker would be called as expected, but the for loop in find_route_worker wasn't even doing anything because balancer->workers->nelts was 0. The balancer would then finally be populated in the new child when the first request hits internal_find_best_byrequests and calls update_workers_node. -- This message was sent by Atlassian JIRA (v6.3.8#6338)
