Having 6 warming serachers is an anti-pattern. What it means is that commits are happening faster than your searcher can be opened. There is _no_ good reason that I know of for changing it from 2, having changed it in solrconfig.xml to 6 almost always indicates an improper configuration.
Places to look: 1> that commits are happening too often, and especially if the commits are happening from a client. If commits aren't being sent by a client, then look at autoCommit and softAutoCommit in solrconfig.xml (if you can). 2> excessive autowarm settings, again in solronfig.xml. If, as you say all of Solr is a black box, then talk to the Sitecore folks, on the surface Solr is just poorly configured.
