How much memory is on the system, and is anything else running?  How  
large is the resulting index?

If you're willing for some queries to take longer after a commit,  
reducing/eliminating the autoWarmCount for your queryCache and  
facetCache should decrease the peak memory usage (as Solr as two  
copies of the cache open at that point).  Setting it to zero could up  
the halve the peak memory usage (at the cost of loss of performance  
after commits).

As yonik suggested, check for PERFORMANCE warnings too--you may have  
more than two Searchers open at once.
