We are running es 1.2.1 cluster on 4 nodes: 4 cores, 14 GB RAM, 1.5 TB disk space, swap disabled. Our application creates daily indexes 2 up to 12 GB in size. No sharding, 1 replica. Currently 200+ indexes (~1.2 TB data). Heap size is set to 6 GB. The main problem is that elastic nodes frequentely (once a day or two) eats up whole system memory and dies. Now it is monitored with monit with setting to restart node on 90% memory usage. It still fails from time to time. Adding new nodes is currently very difficult, so I'm looking for a way to optimize my current setup. Any suggestions? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

I've tried to diable bloom filter for older indexes with no luck. I cannot close indexes, because all of them are used. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Does it seem related to search activity? Merge activity? What does the hot threads endpoint show before running out of memory? I might try to cap the max segment size or use more shards so the segments stay less than the heap size (maybe target 2GB?)
