Hi, We've recently started using elasticsearch(V-1.5) on one of our app & started facing following issues.. - Generating Logs ( Exceptionally very high viz.. 5 min 5GB log ) - High CPU Utilization - In-spite of deleting logs, disk space was not released. Needed Hard boot the server to release the logs space. **System Configuration** OS - Linux 14.04 LTS 64bit Ubuntu. vCPU - 2 Core vRAM - 8 GB Disk Space - 100 GB Don't know what's going wrong. Any clue... -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
