CU is on EAP 7.3 on OCP and has configured the socket-handler as below: <async-handler name= "async-logstash-handler" > <queue-length value= "${env.LHT_LOGGING_BUFFER_SIZE:1048576}" /> <overflow-action value= "discard" /> <subhandlers> <handler name= "logstash-handler" /> </subhandlers> </async-handler> <console-handler name= "CONSOLE" > <formatter> <named-formatter name= "COLOR-PATTERN" /> </formatter> </console-handler> <socket-handler name= "logstash-handler" block-on-reconnect= " true " outbound-socket-binding-ref= "logstash" > <named-formatter name= "logstash-json-formatter" /> </socket-handler> The formatter: <formatter name= "logstash-json-formatter" > <json-formatter> <exception-output-type value= "formatted" /> <key-overrides host-name= "host" logger-name= "category" message= "log-message" thread-id= "thread" thread-name= "thread-name" timestamp= "@timestamp" /> <meta-data> <property name= "@version" value= "1" /> <property name= "lhtappid" value= "2038" /> <property name= "namespace" value= "lht-platform-sample-applications-nonprod" /> <property name= "stage" value= "dev" /> </meta-data> </json-formatter> </formatter> The socket binding : <outbound-socket-binding name= "logstash" > <remote-destination host= "logstash.lhtlogging-nonprod.svc.cluster.local" port= "8080" /> </outbound-socket-binding> When based on network policy on OCP the traffic on logstash.lhtlogging-nonprod.svc.cluster.local at 80080 will be enabled. This configuration works well, however if we disable the traffic the server never get started and throws the following error: 09:47:37,297 INFO [org.jboss.as.connector.deployment] (MSC service thread 1-3) WFLYJCA0002: Bound JCA ConnectionFactory [java:/JmsXA] 09:47:37,297 INFO [org.jboss.as.connector.deployment] (MSC service thread 1-2) WFLYJCA0118: Binding connection factory named java:/JmsXA to alias java:jboss/DefaultJMSConnectionFactory 09:49:06,466 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread ) WFLYCTL0348: Timeout after [90] seconds waiting for service container stability.
