Delete by query running by itself

Elastic Stack Elasticsearch
1

Hi All,

I noticed a strange behave with Elasticsearch. I deleted some doc by using
delete by query and query used for this was a range query over the index
level(es_15). Then I shut down my cluster. when I restarted it, I am seeing
this in log, and its continuously running.

Here "REL_YsUpdateOs" is child type but this type does not have any
document in it. What is exactly happening over here. I am confused. Is it
trying to delete something regarding parent child in context to the delete
by query that I executed before shutting down elasticsearch. And if I
closed the cluster, it is still remebering the last log, although I tried
by deleting the log too, but still got the same error. Please explain me
this behave.

Thanks
