IPv6 system log errors

[JohnDory]

I have been receiving the following errors in the system log of a 7800N (v1.06d fireware) for the last few weeks.
Below is the router log for the last hour. The machines where all turned off for the first 45 minutes of this log.

We use EntaNet as our ISP, IPv6 still works, browsing can be a little slow some times.
It doesnt effect our other router that has IPv6 turned off.
The routers have only been connected this time for almost 16 days, they went down last time due to power failures.
Should we be worried about this and is there a cure

When it comes to these complicated logs, I would normally send them over to Billion support to find out whats going on, thats your best bet.

They should let you know if there is anything to worry about.

I have done now and they've been forwarded, I just though someone may have come across this before.
