# High RSS memory usage due to MADV settings
In versions of Metricbeat prior to 7.10.2, the go runtime defaults to `MADV_FREE` by default. In some cases, this can lead to high RSS memory usage while the kernel waits to reclaim any pages assigned to Metricbeat. On versions prior to 7.10.2, set the `GODEBUG="madvdontneed=1"` environment variable if you run into RSS usage issues.
