> With DocumentDiscoveryLiteService in 1.3.7 the following WARN has been noticed:
> {code}
> 07.10.2015 06:38:16.575 *TRACE* [DocumentDiscoveryLiteService-BackgroundWorker-[4]] org.apache.jackrabbit.oak.plugins.document.DocumentDiscoveryLiteService hasBacklog: start. clusterNodeId: 1
> 07.10.2015 06:38:16.575 *TRACE* [DocumentDiscoveryLiteService-BackgroundWorker-[4]] org.apache.jackrabbit.oak.plugins.document.DocumentDiscoveryLiteService getLastKnownRevision: end. clusterNode:
>  1, lastKnownRevision: r14e0c0898cc-0-1
> 07.10.2015 06:38:16.575 *WARN* [DocumentDiscoveryLiteService-BackgroundWorker-[4]] org.apache.jackrabbit.oak.plugins.document.DocumentDiscoveryLiteService hasBacklog: node has lastWrittenRootRev=
> null
> {code}
> This happens every 5sec. While the warning is somewhat legitimate as it cannot determine the backlog of a not-active instance - it is spam if it occurs every 5sec. So rather than warning constantly, there should only be one warning and then a fall-back to log.debug afterwards.
