Hi I use ActiveMQ 5.13.1.
When I start ActiveMQ, An java.util.ConcurrentModificationException occured, and failed to start MQ. The following log was output. ------------------------------------------------------------------------------------------------------------- INFO | Recovery replayed 1 operations from the journal in 0.02 seconds. | org.apache.activemq.store.kahadb.MessageDatabase | main INFO | PListStore:[/xxxx/xxxx/tmp_storage] started | org.apache.activemq.store.kahadb.plist.PListStoreImpl | main INFO | Apache ActiveMQ 5.13.1 (imapsbroker_push_imaps0, ID:xxxx-xxxx-xxxx-0:1) is starting | org.apache.activemq.broker.BrokerService | main INFO | Listening for connections at: mqtt+ssl://xxxx:8155 | org.apache.activemq.transport.TransportServerThreadSupport | main INFO | Connector mqtt+ssl started | org.apache.activemq.broker.TransportConnector | main ERROR | Failed to start Apache ActiveMQ ([imapsbroker_push_imaps0, ID:xxxx-xxxx-xxxx-0:1], java.util.ConcurrentModificationException) | org.apache.activemq.broker.BrokerService | main INFO | Apache ActiveMQ 5.13.1 (xxxx, ID:xxxx-xxxx-xxxx-0:1) is shutting down | org.apache.activemq.broker.BrokerService | main ------------------------------------------------------------------------------------------------------------- When this problem occurred, MQ was started with multiple connection requests. Is this the cause? -- Sent from: http://activemq.2283324.n4.nabble.com/ActiveMQ-User-f2341805.html
