When the scan was sent ?? Every day, or just one day a week, and that day is weekend or Monday to Friday and at what time ?? Because if the pc´s are not connected to the network when the scanning is programmed, that is why it can be that when it achieves the EPO to see them the scans and consumes so much resource of the equipment
seems really logoff all the login sessions before scan really helps on the problem.
I logged off all the idle sessions on the Windows. The available memory only drops around 60MB after scan
