[mod_cluster-issues] [JBoss JIRA] (MODCLUSTER-97) httpd should remove workers who crashed

httpd should remove workers who crashed --------------------------------------- Key: MODCLUSTER-97 URL: https://issues.jboss.org/browse/MODCLUSTER-97 Project: mod_cluster Issue Type: Feature Request Security Level: Public(Everyone can see) Affects Versions: 1.0.1.GA Reporter: Bela Ban Assignee: Jean-Frederic Clere Fix For: 1.1.0.Beta1 When worker W crashes, httpd will not remove it from its worker tables and still try to send requests to W. We should implement something like ping_mode=I (interval), ping_timeout and connection_ping_interval in mod_jk [1]. It should work as follows: - W crashes - httpd waits for connection_ping_interval of idle time, then starts checking the connection to W every ping_timeout seconds (or ms) - When the connection to W is broken, httpd should remove W from its worker table and stop the connection checker - When (if !) W is started again, mod-cluster will register it again with httpd The configuration above should be done entirely on the AS side, e.g. in HAModClusterConfig. maybe we can find just 1 attribute rather than 3.
