Hello:

The Kibana service fails regularly and when I go to restart Kibana the following errors are displayed in the log:

```auto
 log [21:15:09.874] [error][data][elasticsearch] [version_conflict_engine_exception]: [task:Lens-lens_telemetry]: version conflict, document already exists (current version [4])
  log [21:15:09.876] [error][data][elasticsearch] [version_conflict_engine_exception]: [task:Actions-actions_telemetry]: version conflict, document already exists (current version [4])
  log [21:15:09.876] [error][data][elasticsearch] [version_conflict_engine_exception]: [task:Alerting-alerting_telemetry]: version conflict, document already exists (current version [4])
  log [21:15:09.904] [error][data][elasticsearch] [version_conflict_engine_exception]: [task:endpoint:user-artifact-packager:1.0.0]: version conflict, document already exists (current version [556])
 log [21:15:09.905] [error][data][elasticsearch] [version_conflict_engine_exception]: [task:apm-telemetry-task]: version conflict, document already exists (current version [4])

```

Can anyone decipher what these errors mean? Thanks.

Hi Daniel

Seems to be a known bug, that can be ignored, but of course should be fixed:
