In the last days one of my tomcat servlet, running only a Solr instance, crushed unexpectedly twice.
Low memory usage, nothing written in the tomcat log, and the last thing happening in solr log is 'end_commit_flush' followed by 'UnInverted mutli-valued field' for the fields faceted during the newsearcher run. Right after this, the tomcat crushed leaving no trace. Has anyone experienced a similar issue before? Thanks, Manu
