I’m seeing what appears to be quite high memory use from the Mender client on my device when Mender is idle. Is this normal? If not, what should I do to lower it?

Output from top:

```auto
1523 1 root S 839m 169% 29% /usr/bin/mender -daemon

```

`/proc/status` output:

`/proc/cpuinfo` for my device in case it is relevant:

I’m on Rocko and using Mender 1.7.0.

> Hi everybody. I have a question about the RAM consumption by Mender Client. ¿How much is the normal consumption while it is running as daemon but just waiting between server pools requests? I have integrated it manually in a Raspsberry PI3. It works fine (it conects to the server, updates…), but it is consuming a lot of RAM. For the cross-compilation i used this script [https://github.com/mendersoftware/mender-crossbuild/blob/master/go-executable-build.sh](https://github.com/mendersoftware/mender-crossbuild/blob/master/go-executable-build.sh).
