Confluence 5.8.18 crashing after schedulerError Job

Hello,

since some weeks I'm getting the following error for like 100 times and then the confluence instance is crashing and rebooting (sometimes).

ERROR [scheduler_Worker-3] [org.quartz.core.ErrorLogger] schedulerError Job (DEFAULT.IndexQueueFlusher threw an exception.
