last week I upgraded metricbeat from version 5.1.1 to version 5.1.2.
When I take a look at the memory and also the CPU consumption of metricbeat itself for the last 7 days it seems that metricbeat is continuously consuming more memory and CPU. After restarting the metricbeat process it seems working fine again, but memory and CPU load starts increasing again (see also attached screenshot).
Are there any known issues or hints?
We are running metricbeat on Ubuntu Linux 16.04 and have activated the standard metrics and also monitoring for docker containers.
