> REMOTEQUERY action in HTTPSolrCall ends up making too many cascading 
> remoteQuery calls when all all the replicas of a collection are in down 
> state. 
> This results in increase in thread count, unresponsive solr nodes and 
> eventually node (one's which have this collection) going out of live nodes.
> *Example scenario*: Consider a cluster with 3 nodes(solr1, solrw1, 
> solr-overseer1). A collection is present on solr1, solrw1 but both replicas 
> are in down state. When a search request is made to solr-overseer1, since 
> replica is not present locally a remote query is made to solr1 (we also 
> consider inactive slices/coreUrls), solr1 also doesn't see an active replica 
> present locally, it forwards to solrw1, again solrw1 will forward request to 
> solr1. This goes on till both of solr1, solrw1 become unresponsive. Attached 
> logs for this.
> This is happening because we are considering [inactive 
> slices|https://github.com/apache/lucene-solr/blob/68fa249034ba8b273955f20097700dc2fbb7a800/solr/core/src/java/org/apache/solr/servlet/HttpSolrCall.java#L913

>  while forwarding requests to nodes.
> *Steps to reproduce*:
> #  Bring down all replicas of a collection but ensure nodes containing them 
> are up 
> # Make any search call to any of solr nodes for this collection. 
>  
> *Possible fixes*: 
> # Ensure we select only active slices/coreUrls before making remote queries
> # Put a limit on cascading calls probably limit to number of replicas
