Program behavior (any Java program, not just Solr) becomes completely undefined when you get out of memory errors. It's exceptionally difficult to write programs that have defined behavior in an OOM situation. Not impossible, but *very* hard, so I'm reasonably sure that no attempt has been made in the Lucene/Solr codebase. To eliminate the OOM, you need to either make your Java heap larger, or find ways to reduce Solr's heap requirements. http://wiki.apache.org/solr/SolrPerformanceProblems#Java_Heap Thanks, Shawn
