One of the networks I scan with GVM is a network with office computers. This means that during the scanning process, the user can either turn off the computer or take the laptop to a meeting (disconnecting it from the network). In each such case, there are still scanner processes trying to perform further vulnerability scans. It takes ages. Is there any way to stop the disconnected computers scanning process?

Mark host as dead if going offline (failed ICMP ping) during scan
which can be found in the following VT preference:
