[Equip] Attn: Netdog - Neighbour Table Overflow

This has been reported on the Comcast site forums ( »forums.comcast.com/t5/Ho ··· 9/page/3 ), and discussed there by ComcastTuska, who has been investigating, but to no result. The errors occur only with Comcast, and this has been determined by many, including Merlin, to be a Comcast issue. The theory is that it has to do with the way the Comcast nodes are configured, and that certain types of packets that should be suppressed, are not. Can you please look into this? Thanks.

This error has been happening for months both parties are blaming the other, no one has definitively proven it is a comcast issue that I can find. Its a linux kernel error, known to happen with IP6 enabled on large networks after kernel 2.4, one person claims it is when NAS is in use, others are having it with tomato firmware, I have a simple home network and do not see it on my asus router logs anywhere since Dec. 31 off an SMC dory in bridge mode. I am assuming this is an issue with SMC business ass services, since thats the only people who shoudl be parsing a log for data. That or you need something to do at home and are just too damn bored.

Other posts from users have indicated they used a NON asus router and did not get the errors only the asus router did, so its not a clear cut issues that I have found yet.

Also the link below seems to have fixed it following standard linux directions for this error not sure how exactly, but..

There were some mentions of Linksys and another brand also getting the error. I am using Merlin firmware, not Tomato. Merlin firmware provides a system log. He (Merlin) has researched the issue and found it to be Comcast only. I tried the various posted fixes, but none worked. The problem occurs every few hours.

I have been looking at this along with the Netgear Issues..
