FVS318 - Intermittent Network Drops, Began Recently
Hello all,
We have had an FVS318 for about 6 years or so without an issue, until about 2 weeks ago. All of the sudden, about three times a day the entire network will drop and then restart all in the span of 30 to 60 seconds. Any programs that were accessing network resources at that moment will crash. It only seems to happen about 2 to 3 times a day. No settings have been changed on it recently and I am rather puzzled as to why this is happening. The log(listed below) on the VPN shows that the date/time has been reset during this outage. I have searched the internet and come up short. Any ideas would be greatly appreciated!

- Which version router do you have?
- This maybe a little bit too late to help, but I noticed almost the exact same problem with my Cisco rv016 when my cable company changed their backend. The new backend (Arris c4) was sending 100 packets/sec to my rv016, so it would constantly reboot thinking it was under attack. Seems like the same thing might be going on with the snippet of the log you posted.
