mod_cluster subsystem add operation attempts to start services prematurely -------------------------------------------------------------------------- Key: WFLY-10473 URL: https://issues.jboss.org/browse/WFLY-10473 Project: WildFly Issue Type: Bug Components: mod_cluster Affects Versions: 13.0.0.Beta1, 13.0.0.Final Reporter: Radoslav Husar Assignee: Radoslav Husar This has been a problem multiple times in the past. Even a single subsystem add operation like {noformat} [standalone@localhost:9990 /] /subsystem=modcluster:add { "outcome" => "success", "response-headers" => { "operation-requires-reload" => true, "process-state" => "reload-required" } } {noformat} causes failures {noformat}10:28:15,128 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 54) WFLYCTL0013: Operation ("add") failed - address: ([("subsystem" => "modcluster")]) - failure description: "WFLYCTL0155: 'connector' may not be null" 10:28:15,135 ERROR [org.jboss.as.controller.management-operation] (ServerService Thread Pool -- 54) WFLYCTL0013: Operation ("add") failed - address: ([("subsystem" => "modcluster")]) - failure description: "WFLYCTL0155: 'connector' may not be null" {noformat} This is fixed also as a side effect to supporting multiple configurations. Since boot time handling is required, most operations on the subsystem need to leave the server in the reload-required state.
