I solved the problem by replacing my 10+ year old router/modem which was letting DOS and DDOS attacks through and crashing my FBX within a day or two after rebooting or reinstalling newest FBX image. My system has been up and running every since installing my Netgear CAX30. I subscribe to their Armor A.I. service that learns about attacks and blocks them. Good Luck.
