I seem to remember a recent java released fixed seemingly random SIGSEGV's causing Solr/Lucene to crash non-deterministicly. http://lucene.apache.org/solr/#26+October+2011+-+Java+7u1+fixes+index+corruption+and+crash+bugs+in+Apache+Lucene+Core+and+Apache+Solr Hopefully this will provide you with some answers.
