Logs full of 'BR_LAN:LAN Neighbor Discovery : Host ' messages

Hi all,

 

I have the new BT Smart Hub for about 3 month now, all seems to be ok but about every few weeks it does a reset. Normally after I check the logs and see a message that hub is going down in 3 seconds or whatever, so I know its not a line failure.

 

Anyway, this time I notice that I have a huge amount of these messages (see below) at very regular intervals. So regular (6 or 7 per minute) that there are 131 pages of them!

Exporting my log of just those messages shows I have over 15,200 of them since around 2pm on the 31st of May 2017!

So, what are these, should they be there, should they be this regular.

Anyone any ideas.

Thanks

Martin

Re: Logs full of 'BR_LAN:LAN Neighbor Discovery : Host ' messages

Looks like the hub is somewhat overzealous in logging these.  It's normal, you could have a look here for a quick explanation.
