Every week night our firewall comes up with the following Event ID message and stops the service.
Event ID: 5001
3Com Etherlink Server 10/100 Dual Port A#2:Could not allocate the resources necessary for operation.
The Firewall has to be restarted in order for it to work again. This happens every 'week' night at 9pm but not at the weekend.
The only time the error didn't occur is when I pulled the network cable of the relevant port out one night just before 9pm.
