Hi! when is used a JDBC Journal the JDBC Node Manager will use an optimistic Lock with timeout (similar to the ActiveMQ's http://activemq.apache.org/maven/apidocs/org/apache/activemq/store/jdbc/LeaseDatabaseLocker.html) to maintain the ownership of the Journal. This lock periodically renew the lease on the Journal and warn if the renew operation will take more than what is expected (4000 ms I suppose) to be triggered/happen. The reasons could be very different including DBMS latencies/heavy GC pauses/too many threads vs CPU cores. More infos are here: https://activemq.apache.org/artemis/docs/latest/persistence.html on dbc-lock-renew-period field.
