It "sounds" like you might be reaching the RAM limits of your hardware based on your searches. I'd probably try to analyze your searches and (re)size your hardware appropriately. First thing to check is how much fielddata you are using for typical daily queries:
curl "localhost:9200/_nodes/stats/indices/fielddata/*?pretty" 6GB allocated to ES on a 7GB RAM is probably a bit too much - need some breathing room for OS and file system. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
