I tried the stats_over_http plugin today and it's behaving the same. memory/hdrHeap and memory/hdrStrHeap are increasing on every requests.
Will file an issue. Not only a Virtual Machine issue. Tried to get jemalloc to help us but I believe we failed. No output. How to reproduce? #!/bin/bash while true; do curl http://<ip>/_stats >/dev/null done Steve On Mon, Sep 10, 2018 at 7:21 AM Steve Malenfant <smalenf...@gmail.com> wrote: > Ever since we upgraded to 6.x or 7.x, it seems like we have issues with > memory utilization climbing over time in a 4GB VM.
