title: When loading indexes in elasticsearch, I seem to be hitting a physical limit?
body: <p>I've loaded an index which contained 28.7million records, but only 18.4million were loaded. No errors have been reported in either logstash (used to load the data) or in Elasticsearch. I've tried to load the same file again, but it only managed to load 4.5K records. Again no errors have been found. </p>
  
  <p>I've deleted all three indexes created and tried to once again load the file, but this time, it isn't loading any documents! Therefore it is safe to assume that I am hitting a physical limit of Elasticsearch, but I cannot find out where and what this limit is.</p>
  
  <p>My server is a dual core Xeon backed up with 8GB of memory. I have 140GB of disk space free. The elasticsearch config file has not been touched since the install.</p>
  
  <p>Any advice would be gratefully received.</p>
