==== High RSS memory usage due to MADV settings
=== High RSS memory usage due to MADV settings

In versions of {beatname_lc} 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 {beatname_lc}.
On versions prior to 7.10.2, set the `GODEBUG="madvdontneed=1"` environment variable if you run into RSS usage issues.
In versions of {beatname_uc} prior to 7.10.2, the go runtime defaults to `MADV_FREE` by default.
