Container? Are you on K8s?

You need to check on why the container is crashing inside your VM, most likely excessive use of resources (e.g. Heap).
If you recently raised the JVM heap, well, that could be the reason.

Hi Luca,

     Thanks for you reply. I checked resources on container is its not crashing but it keeps reindexing in loop.

      it finish the reindex successfully but after that its unload the plugin and also clean it as per logs and that happens in loop.

    
       as you can see in logs  message "Index changes in version 82 is ready" but after that its unload the plugin and start the reindex process again. 

      
Reindexed 36106 documents in changes index in 631.5s (57.2/s)
Index changes in version 82 is ready
