Hi @Maron
I got news for you regarding this issue. Its actually not a bug but designed as it is. The restart of the automation-core will happen if an app, which is not signed is installed and provides a bundle with the slot "automation-bundle-v3". So this happens for all SDK-samples and for your own project (as long as the app is not signed).
Background: The app rexroth-automationcore restart is initiated by snapd or systemd because the SDK samples snaps are not signed. The restart of rexroth-automationcore occurs on first install of any unsigned RT-SDK snap in order to connect the content interface "automation-bundle-v3". So that the rexroth-automationcore is able to access the bundle provided by the unsigned snap. There is no restart on update/reinstall of the snap. There will be no restart when installing an app for productive use since these apps should be signed.
