Vigor 3900 Coprocessor CPU 100% was created by rcookdps
Since updating to firmware 1.4.4 the co processor CPU has maxed out at 100% on two occasions in the last week. All VPNs stop working when this happens, tunnel shows as up but no traffic.

The only way I can resolve the issue is to reboot the firewall, once rebooted the VPNs dont work and I have to manually start the service using the web console - restart IPSEC

Is it possible to downgrade the firmware on these firewalls?

Opened a support ticket with Draytek and they advised I downgraded the firmware back to 1.4.3
