In the Models-tab in Model Manager, the Activity column has two possible values: **Idle** and **Processing**.The activity status is Processing if a server operation like Share, Receive, Reserve etc. is going on. If there is no server operation going on, the status is Idle.Sometimes a server operation is within a transaction that is never resumed by the client. In this case the server waits for 24 hours before killing the process. In the meantime the activity status is Processing.
