I keep getting this error in my logs "ipv4 neighbor table overflow, please consider increasing max-neighbor-entries"
6.43.7 firmware (Although I was seeing this less frequently on 6.43.3 the previous firmware, by less frequently I would see this in the logs maybe 6-10 times in a day.)
The router was left at the default max-neighbor-entries of 8192, but I have tried changing it to higher and lower numbers with no change. When I try increasing the number there is sometimes a delay before the error reoccurs.
At the moment I am getting this error in groups of 6-8 that all come in within a second and each group will happen several times a minute. Sometimes I will only get the error alone though, no idea what the correlation is... Sometimes I only get a few single errors over several minutes to an hour.
Neighbor entries are at 140, sometimes 139, though no correlation there it seems.
ARP table is at 306 with little variance.
Nothing new connected to the router, maybe a customer router?
There does not seem to be a correlation between neighbor entries expiring and the log occurring.
This tower is pretty similar, in config and hardware connected to it, to most of the rest of my network and none of my other routers are doing this.
More then willing to provide any other information if it might help.
Thanks ahead of time for the help.
