> Key: SOLR-7614
> URL: https://issues.apache.org/jira/browse/SOLR-7614
> Project: Solr
> Issue Type: Bug
> Reporter: Yonik Seeley

> Fix For: 5.2

> I just happened to notice the following added to FacetComponent:
> {code}
> /**
> * Incremented counter used to track the values being refined in a given request.
> * This counter is used in conjunction with {@link PivotFacet#REFINE_PARAM} to identify
> * which refinement values are associated with which pivots.
> */
> int pivotRefinementCounter = 0;
> {code}
> That counter is incremented for each refinement request for correlation, and then reset to 0 at the end. This will obviously break for concurrent distributed pivot facet requests.
> pivotRefinementCounter should be moved to per-request storage.
