ES v5.6.5  
This in on a server that is heavily indexing all of the time. Refresh interval is set to 1s, and honestly before the last 2-3 months, this has never been a problem (possibly earlier version of ES). All of a sudden, roughly 10% of my queries (even running the same query over and over) will take \> 1-2s. The majority of my queries are ~40ms.

I am using has\_parent in all of them with an inner hits size of 1 (one parent to many children). Any help would be appreciated, please ask for more info if necessary.
